For what is worth, I was in a deep depression for three long years. I lost the will of living.
This forum did wonders to help me thru when I even lost my friends (my fault).
I had a change in medication, basically a reduction and one SSRI, Paxil.
I was always reluctant to take one. Tried everything under the sun avoiding them. Mainly from what I heard. The horror stories.
One day, I'm thinking and realize that I'm living the horror trying to avoid it.
What I'm a going to lose if I try one?. Absolutely nothing. That's exactly what I was. Nothing.
So I stopped wellbutrin and decided to try an SSRI. Paxil and my mindset changed the situation.

I dare to say that I'm happy. I have new interests. I went back to my old friends and picked on my old hobbies.
People didn't abandon me. I abandoned them. I didn't want them to see me so sick.
They all new what was going on, but were respecting my position.
Sometimes we are worth more to people that we realize.

Two sudden death of friends reunited us again. Life is funny. It has really misterious ways.
Your time will come to shine again. And looking back you will regret the time lost. At least I do.
Yes, there is a come back. Yes, your life will change for the better. Just hang in there and don't let it get worse. That's enough for now.

If is not worse is has to be a little better. Take baby steps towards insignificant things. Like nature. Not judging, just observing. You have a place in this world. That's why you are here. It's a matter of time. Good luck.
