There is so much ahead for you that is good. I know you can't see or feel it, but please try and believe it. Lean on all of our knowledge here at PC...
Yes, you want it to stop. Whenever someone is depressed so severely, they do indeed need LIFE as they KNOW IT to stop... but not to die... to CHANGE.
There are numerous things you can change, but right now the only thing you might be able to do is begin to change how you are thinking about all this, ok?
Thought stopping will help. When you notice (if you can) that you are thinking something negative, stop the thought. Try to replace it with something else.
At the top of the psychotherapy forum is a thread on the 10 common cognitive distortions. Please read and reread it. Depression lies to us..."he" tells us lies... and the way out of the choke hold it has on you is to begin working on the lies it's told and correcting the thinking.
You can make it...you can make changes.
