Jenny I don't think your nuts I have been where you are at and I am grateful my well thought-out plans didn't work!
When I start to feel hopeless I come on here, or I reach out at an AA meeting.
I know how hard it is to turn that kind of depression around that is why it is so vital to get some help from a professional.
I know in every state they have confidential hotlines you can call and they can give you names and numbers of people who will help.
You said you were going to call someone, after you do will you come back and let us know how you are and if it helped?
Please come back I'll be waiting to hear from you. Peace my sister
