I think my friend is having a nervous breakdown

I think my friend is having a nervous breakdown and i need help with how to help him.

Some background my friend (lets call him Mike) has always been a bit negative but a very outgoing guy and always up for a good time. He sometimes gets a little too worked up about little things more than he should. Nothing alarming that would make Mike's personality would stick out from any other of my friends. I did from time to time get the sense from him he was a little frustrated with life and a little unhappy.

Mike and I and bunch of our other friends had a few drinks on a Sunday about 3pm-9pm, nothing major, i'd be surprised if anybody had more than 3/4 drinks over the course of the day. Mike was doing a dry January but quit on Friday night and was drinking on Sunday. He seemed completely normal all day and when i said goodbye to him on Sunday night.

I sit in the cube next to him at work. He emailed in sick on Monday morning sayng he was feeling off, nothing too alarming. This morning (Tuesday) he came in about 9am and I said Hi and i was in the middle of some work so i didn't notice anything off about him. He disappeared most of the morning which is the norm as he usually has more meetings than me. But at about 1pm my manager (also Mike's mgr) calls me to meet him in his office so i do.

He starts telling me that Mike is acting very strangely and he has taken separate impromtu meetings with him, another manager, another manager and another friend of ours. All the people he meet with are friends outside of work and we are a close community. My manager tells me in his meeting with Mike, he was extremely erratic and agitated. He was talking about work issues of how to fix how the office operates to personal issues to politics and making very little sense and he was worried, he wanted me to talk to him and take him home and tell he can take as much time as he needs. I was shocked by all my manager was saying to me, all this came out of the blue. Another manager took Mike to lunch in the meantime.

I called Mike's roommate to ask him if he noticed Mike acting weird. The roommate said he started acting weird on Sunday night. Basically saying he was acting erratic talking about different subjects and making no sense. I asked the Roomate did he know what could have triggered this? He said Mike called his mom on Sunday night and its the 3 year anniversary of his dad dieing. I've known Mike more than 3 years and he never told me his dad had died. He never mentioned his dad and i never even thought anything about his dad, it never came up in conversation. So kinda alarming he's never talked about his dad.

Mike came back from lunch and i asked him was he OK? He said yeah, got a lot of stuff off my chest today and that he's going home. He looked super tired to me and i asked him did he want to get a coffee, because i wanted to make sure he as ok. We went to a coffee shop across the street (we didn't have coffee just sat down) and i called another buddy from the office to come.

Initially Mike was erratic when speaking, even slightly scratching himself. He made no sense at the start of the conversation. He slowly came out of the nonsense, talking about how he pictures everything so negative, he talked about the stress of the job, how he's stressed every night and smokes a ton of weed to relax every night, using it as a crutch. He talked about all the pressure in working building up over the past couple of weeks (everybody was a little surprised as honestly the projects we are currently on, aren't that stressful). He talked about the new girl he was seeing, and he didn't want to become BF and GF because he kept seeing all these negative things about her and that he thought he was horrible to her. He also talked about having a high of the girl being nice to her and that triggered this reaction as he's used to the negative. He talked about how everybody sees him so poorly (he's well respected in work and outside). He mentioned his dad's death as cross he bares. He said he hadn't slept since Saturday night. We spoke for awhile about how he was overthinking everything, he just needed a break and need to focus on some of the positives in his life like the trip he's taking next month with the gf. At times we tried to talked to him but he was just staring off into space and then he would comeback completely changing the subject.

Sorry if the above is all over the place, I'm just trying to remember all the things he said. It seemed like a million things hitting him at once.

We went for a walk and got some food as he hadn't eaten all day. He was a little more in tune with us and engaging us in general banter. He started to crash out from the tiredness so we got him a cab home. I called the roommate to give him the latest status and that he was on his way home. The roommate texted me to say he went straight to bed.

The roommate said he'll work from home tomorrow and make sure he's ok. The roommate has Mike's sister and mother's details if he gets worse.

Any thoughts and tips on how to help him get over this? I'm hoping its just a bunch of stuff hit him at once and a good nights rest will fix a lot of it and maybe he should get some consuling so that he doesn't bottle things up. But it was very scary to see your friend acting so erratically and completely out of character that it could be something worse.

Thanks for taking the time to read the above.
