I found the trick isn't to suppress my negative emotions, it was to learn how to effectively express them, or accept them and then channel them in contructive ways. Lots of work but well worth it.

I've been happily married 10 years now. But I spent many years being depressed and just plain crazy. When I was not happy with myself, when I had not yet found medication that helped me, when I had not yet accepted (or knew) who I was, warts and all, I was not very successful at all in my relationships. They just brought me more pain.

I spent almost a decade alone and uninvolved, working on myself and trying to get me better. Once I was in a relatively better place, living and being okay with my depression, with me and all my faults, with the fact I needed medicine every day to be okay, then eventually I ended up in a very satisfying and loving relationship. Like everything else in life, it's not perfect but it's a good solid marriage with someone I can live contentedly with, be myself around, day in and day out.

If you don't give up on yourself I believe the same can happen for you. But you have to work hard, stick around and stay alive for the good stuff to happen. In the mean time YOU be your own best friend and love yourself, work hard at making yourself healthy.
