I have been/still am in a quite similar situation to yours, except I am a 50nl player. Around 6 months ago, I was completely sick of everything, because at that time I was sick for 1 year (kissing disease), which resulted in being socially isolated sitting in front of my computer doing nothing, since I couldn't do all the stuff in life that I enjoyed. Think about
: party, sports, meet up with friends, girls, holiday, poker (too tired) etc. I started taking some very big steps, and one of those things was therapy because I felt I couldn't sink any further/deeper. I started taking small steps with a lot of stuff in life (sport again a little bit, meet some friends, go out till 0:00 etc), and slowly building my life again. Only reason I am saying this, is to show that I know how you feel/felt.
So here comes my advice, that you might find a little bit strange, but this helped me the most for sure, even more than the all therapy and conversations I have had, and trust me, I felt really really really bad / depressive at a certain point.
Go into the pickup artist world.
You might think now ''but well, I don't want to get girls'', but that is absolutely not what it is about. It is about improving yourself as a person, which results in more success with women, but even if you don't care about that, it will still improve your life. Especially the writer of the famous book ''the game'', Neil Strauss, has been a huge inspiration for me. He did turn his life around for a full 100%, and also explains how to do it yourself, taking very small steps, writing down certain points you want to improve, updating them, and so on. If you are interested in it, just pm me your Skype, and I will introduce you to it. Trust me, it is very very good advice, and goes really deep. It is not as easy as ''write down goals, and do it''.
This is the first part of a really nice dvd series, that will help you a lot.
Wish you all the best man.
Also, I think this is the best read I have had in a long long time, especially to make me realize I am not the only one and to realize I made the right steps so far.
