Suicide

I've never posted here before - I'm a 34 year old parent of two little girls. I have a successful job, lovely home, etc etc. I've been deeply suicidal before - in fact I was hospitalised for 6 months about 7 years ago because of it. Right now I'm done. I've gone past 'oh they would be better off without me' to the point where I think, fuck it, who cares? I'll be dead? I don't have to deal with them feeling sad. I have a plan, just deciding on the date. I'm so tired.
