I guess most of us here have been in your shoes. I know it feels so bad now but give it a little time and it will hurt less.
Just get on here and find somebody to talk to.
Think of other things rather than "ending it all". If you have a pet, cuddle up with it; they are great stress relievers. ( Might not work if you have a fish, though):-)
Take a walk, take up a hobby; I am going to try doing some stained glass projects.
Just anything to take your mind off of it. Best wishes with it. Write to me any time you like. Take care of yourself, Lorena
