I survived a REAL crisis! But what's next?

After my mother died 2 years ago, I quit my job and started a record label with a friend of mine. I thought I was going to take over the music business... however, after only a few weeks I began believing something was wrong. I just couldn't identify what it was... I had difficulties sleeping, couldn't concentrate... soooo scared the business would go wrong. "OMG, what's going on, I can't afford to fail.. keep going, keep going... " was all I kept thinking... Then, for some reason I felt that I had to spend myself to success. it was silly I know- buying expensive suits, a new BMW... I left my girlfriend, at first blaming her for my panic attacks, that she wasn't helping at all (in fact she's been faultless). My business partner was beginning to be irritated, too.. well to cut it short: we were lucky, and secured a few record deals. A year later, things have improved a lot. I know I've been acting recklessly.... but this is not why I came here. I would like to find out how you would approach a difficult period in life, if you were me... the next time around. Would you seek treatment? Honestly I am still scared. Scared, that I may happen again, and that this time I won't be as lucky... so, I guess I am scared of my anxieties. It is crazy, no? Thanks for your time, sir. Buster
