I have been there, the feeling that you have no where else to turn. Backed into a corner with no way out.
The thing is it's not real. The corner is in our minds, we are not using all our experience or even all our brain when we create these worlds.
It's not even our fantasy, it's someone elses. Someone put it into us long ago, whether that was a parent, the Witnesses or both. They said we are worthless, that by ourselves we are nothing and will get backed into that corner.
It isn't true. You and I are beautiful. Ending our lives by choice is the tragic sudden and needless end to something wonderful.
I hope you reconsider, and find people that will let you know who you really are, because at the point you are at, you need others to convince you of this.
PM me if are interested in talking.
