Unbelievable. Now I really feel a part of GTP. I didn't think that I would get that much sympathy from you guys, thanks. I always thought that I was just a member that wasn't noticable, kind of invisible.
Not at all. I can't speak for everyone, but to me, you're one of the many instantly-recognizable regulars around here. That may be in part because of your rather memorable avatar, but it's also because you're a valued member of the community. 👍
Some of the other members here have given you some excellent advice and resources, so I'll just say this: Suicide isn't so much a solution to depression as it is a means of passing it on to those around you -- your family, your friends, and even your e-friends like us -- who will then live with the sadness of losing you.
Now, I know you're kind enough and smart enough to not want to do that, so you have to go about fighting the problem a different way, which means medication, going to the gym, whatever it takes. You've told us that your friends think you're a strong-willed person, which is great -- that means that you'll have the determination to work with your doctors and beat this problem.
I don't know much about psychology and the physiology of the brain, but for what its worth, might I suggest harnessing the sadness that you feel and converting it into something constructive? Other than going to the gym, perhaps you can spend time painting/drawing whatever comes to mind, or playing music. For me, after a rough day, playing the piano can be very soothing, especially if I begin with loud, angry songs, tapering down to eventually end with softer, happier ones.
As MachOne said, just keep on truckin', mate. One day, you'll be able to look back on this period of your life, and you'll be proud to have emerged victorious, happy, and very much alive. Beating life's problems is what life's all about. 👍
