Future career paralysis

Hey, I want to go back to university to do a masters degree. I've already applied for a degree but I'm not really sure I want to do it. You see while it would provide me with a creative outlet in an industry I want to break into with hard skills I just don't seem to have the motivation to prepare for it to the extent it requires. I've already done some preparation but its so hard to focus because the course is practical nuts and bolts and so is the prep and I'm fairly abstract myself in terms of how I think and go about things. Then again I feel once I get over that hurdle it could be satisfying because I could put my ideas into reality.

On the other hand I've considered applying for a degree in an unrelated area but one in which I already have a BA. I did very well in this as I was interested in it but there isn't much outlet for creativity, which is essential for me. I would be definitely set on doing a PHD in this afterwards. I really like research and the college environment. But I feel I'd be selling myself short, like I didn't have the courage to take a risk and go out and make my mark on the world, I'd just be hiding in the safe confines of a university.

So therein lies the problem. I'm trying to figure out which option incurs the greater penalties based on current information which is somewhat unreliable. Since leaving college I haven't thrived at all. I've worked but hated it, well the job I'm in. Had to go with part time because it was stressing me out so much. I lost my friends moving to different countries. I've tried to expand my social circle by doing courses etc with no luck. So I don't know whether taking the second option would just be one borne out of nostalgia for better days in the past. Or whether my lack of motivation is a byproduct of the entropic situation I'm in, entropic because everything seems pointless, I worked hard in college and had several ideas of what I'd do upon completion but nothing materialized except an unrewarding job completely unsuited to my personality and the loss of a social circle. It was horrible because I was back at square minus one. So my next decision is fairly serious, I don't want to mess it up this time. I suppose if one doesn't work out I'll have the other option but I want to avoid that outcome.
