Sixteen years is a long time to suffer, I'm sorry you've had to go through it. You are not alone. I have been resisting suicide since the age of fifteen or sixteen and I'm now fifty one. It's my mum who is keeping me alive. I'm trying to hold on until she dies.
I know you said you can't take the constant crying - have you tried any medication for depression? Meds can be surprisingly effective. I have schizoaffective disorder, which is schizophrenia mixed with bipolar disease, and without medication I would, like you, be crying all the time too. I went on to my current antipsychotic and antidepressant about six or seven years ago and have gone from crying my eyes out every other day to not crying for years - literally years. That's some badass meds. Im not saying you need an antipsychotic but you might need an antidepressant.
It's sad for you to want to be persuaded into suicide but in this forum I don't think you'll find people trying to persuade you to kill yourself. People in here will support you with whatever decision you make but they tend not to actually persuade you to ctb, the actual decision to go ahead with it or not is yours alone.
