This is relatable. I hate the thought of my family finding out, that's been a factor holding me back. I am only willing to do it now because I'm not living at home so my family wouldn't find my body, and I have a sister so I know my mom would stay safe for her (she's very family-oriented and would be worries about her safety in the aftermath otherwise). Some people will still be hurt by my decision which I abhor, but I'm also hurting people by not doing it, and I also just can't wait any longer
Realizing my reply was only self-focused, so adding on:
It's clear you care a lot about your family, and despite your intense pain and distress, you care about how your potential suicide would impact them. That says a lot about your heart and character, in a good way. I hope you find peace and comfort, whatever you end up doing
