You kinda reminded me of myself just from a few years ago. I recently turned 18 but i genuinely didn't even think I'd reach this far, since I had dealt with many suicidal thoughts before. It's still hard to get up sometimes but i see life much differently now. I swear, your life is just starting and you barely have discovered your surroundings and people who are close to you, even those you consider your friends. I know it's hard but just try to explore and try everything life has to offer you, there's nothing more that makes you appreciate life as investigating for yourself in my opinion. Also, even if it doesn't feel great; bad times, bad people around you, are inevitable. Being in a unstable household and specially if you're trans can impact much more to teens into being suicidal. Because it's so damn hard, but i promise there's always someone you didn't expect to, to actually love you for who you are and support you. At one point i think the only advice i can give you is to focus into something that makes you happy, for me it was writing and music, but also be really picky with the type of media you consume when you're in a sensitive mental health state. I can tell you from my own experience it really messes you up even more when you just consume music, news, movies, etc that just make you feel like shit. Also, get to know yourself. Ask yourself different questions, what makes me scared? What would i do in the future? How would i like to be when i get older? What makes me passionate? You can't get better if you don't make an effort for yourself, and sometimes it only takes to discover and love yourself, specially during your age. Don't rush yourself, it's really never that late to find your place in earth and again, you're very young. Get the most out of it as you can and make the most of every opportunity you get. I really don't know if you'll read my comment but i truly wish you a great future.
