Yes and no. Ideally I would like help with how to heal and get better even though it's been years of this. I want my parents and family to feel love for me as I haven't gotten that need fulfilled by them since I was a child and support me through a journey to get better. If all my problems could go away and health issues and I could heal my heart and get better I totally would choose life. There's a lot of things I would like to do in life but haven't been able to due to lack of resources and my health. I haven't gone through with a suicide in years because I'm worried my health, body, and situation will end up worse than it is. I believe if I attempt and fail that would be reason enough for my parents to put my in a psych ward for life they'd also never visit me I also don't want my health to decline any more than it already has. I've learned through the years that throngs can always get worse than you think of what is is now.
Ah OK. If I'm hearing you right, what you want most from them is love and support. It might not fix your health and financial issues, but it would go a long way towards feeling optimistic about living. At the moment, you don't feel like you are getting that love and support. They think you are trying to manipulate them by making up stories about being suicidal and therefore dismiss many of your complaints as attention seeking.
I think you'll find many here who can empathise with your situation - these pages are riddled with similar stories. And it's a community that does the best it can to provide love and support to people just like you. It's never going to be the same as getting it from your parents, but hopefully it helps a little.
As for solutions, I really don't have anything solid. My hunch is however cold your parents seem, they must still love you. It's in there somewhere. If they think you are trying to manipulate them by threatening suicide, then all I could suggest is focusing more on what is getting you down, what's within your control to work on and what you feel you need from them in order to move forward with life. Rather than focusing on the suicidal thoughts so much. And see if that makes any difference. Failing that, I'd just try to love them as well as you are capable without any motive. If they don't feel like they are being manipulated into giving you love and support, but instead just reciprocating what you give them, they might open up a little. And even if they don't, you might feel a little better about yourself.
And if worse comes to worst and you decide suicide is the only option, at least you'll know you gave it your best shot, and there's a community here to help with that avenue too.
