I agree - call someone to talk this out - try to schedule an appointment that is sooner and tell them what is going on - they may be more apt to try to fit you in. I know how it can be to feel that way and just the feeling warrants you to seek help, you are completely justified in doing so. I wish you the best!
I have wanted Not to be in the world as soon as I realized I was. I have had a lot of joy in my life I have beautiful, loving ,fantastic grandchildren, Wonderful husband, Great church and friiends,large supportive family
But the common thread that has haunted me is not wanting to be here,I too have wondered where is that fine line in the sand that some people cross over and don't come back.
Would I ever NO,But what concerns me most is that I can get so delusional to even have those thoughts.
I also know that bi-polar depression left untreated can and does take lives.
I have in the past called the crisis hotline and those people were great talking me down and getting me back to a place of emtional soundess.
So please call someone asap,you don't have to suffer in silence.
If your thoughts are edging in that direction its best not to judge for yourself and see if they get worse. I would schedule an appointment as soon as you are able to and if they are not available in the meantime give them a call and explain what's going on.
