Relationship over - Nothing to live for

I don't even know how to start this...

I was going out with this amazing girl whom I felt that I could share a future with and we often discuss and felt the same. When together we had a great time and were very happy

The problem I let my ex girlfriend stay in my house and it led to problems within the relationship. I couldn't just turf out the ex as she was very venerable and had no home to go to! This went on for almost 6 months.

Last week I was given an ultimatum to get the ex out or else me girlfriend was walking, Sunday was the deadline. I finally got my ex to leave and got her out of the house but I didn't get all her clothes out until Monday, as a result I did not live up to the ultimatum. My girlfriend has left me.
There was some issues before then, where I got caught between the ex and girlfriend and was put under huge pressure, so this was the last straw

Now I find myself with no one and I’m thinking of just finishing life, my girlfriend was everything to me, but she won't even talk to me. This I believe is caused by some family members that have returned and has always influenced her. She now tells me that she is humiliated by nit having my Ex out of my house before now

After leaving, the ex was concerned about me and left work early one of the days to come to my house and find I was in the process of hanging myself, she was about half an hr to soon. She totally freaked! I need to end life soon as I can't take the pain any more. I'm being chewed up inside and it's not good! I can't think straight. Someone please help me...
