I'm not trying to encourage you to CTB or to end your life but, as far as going to hell because you died by suicide?
For what it's worth, those who have had near death experiences, or NDEs, as a result of a suicide attempt have all reported that they were treated with love and understanding and had positive experiences.
Those who feel that they've had after death communication with loved ones who have died by suicide have all reported that their loved one is in a good place and not being punished.
Bill Guggenheim has had an interesting road to developing his psychic abilities and also shares his experiences after his daughter died by suicide.
Here's a link to a good video of him discussing his experiences and his experiences with his late daughter.

Those who have had near death experiences overwhelmingly report that there is no hell. That hell is a made up concept meant to be used as a scare tactic.
A life review? Accountability? Yes. Hell? Eternal damnation? No.
The only NDEs I've come across that talk about hell are usually a product of either a religious organization or an individual who says to take Jesus as your savior or else. There's usually an agenda in reports of hell.
For what it's worth, here is a link to video of a psychic medium, she had her own experience with depression and a suicide attempt, and her experiences talking with those on the "other side" who died by suicide (hint: none of them are in hell).

Here's another suicide attempt account of an NDE that does not involve hell.
People who suffer from mental illness, whether they have bipolar disorder or clinical depression, do not get the same kind of understanding that those who suffer from an illness or disease of the body.
If a person who has stage four cancer opts to stop treatment that is not regarded as a suicide.
Their deaths are more easily understood, their decision is accepted and respected and people can accept their death more easily.
But we still see those who suffer from an illness of the mind and who opt to end their suffering because no amount of treatment can end their pain or make their lives bearable as someone who killed themselves.
People who suffer from an illness of the mind should be able to have the same reassuring conversations with their loved ones that those who have an illness of the body are allowed to have.
Maybe suicides would not leave the same level of grief if this were the case.
Canada has added mental illness under their right to die laws.
There are native cultures who believe that suicide means it was that person's time to go, just as in the case of a physical illness.
So, if there is an afterlife and a God, I do not believe that those who die from an illness of the mind are punished any more than a person who died of an illness of the body.
We're still woefully behind in understanding the full impact of mental illness but that doesn't make it any less of an illness or any less of a fatal illness.
Having said all that, I'll leave you with the genuine wish that things get better and that you find the answers and relief that you need.
If your situation is really to the point of no return then I respect your feelings, I respect your decision and wish you a peaceful transition.
