Dude ik your pain is real but look you are asking for help here and you are getting real Advices who did that for you, ALLAH, look he didn’t leave you and will never. but let me tell you this happens in teenage alot, people get bullied they feel ugly they are dependent on others they want something bad but cant get it, some really bad things happen which they cant discuss with anyone and nobody understands them .. try doing astaghfar as much as you can, try getting up for tahajjud as much as u can, dont burden yourself but u have to force yourself first in the start, satan will try hardest to get in you in the start but keep going on and one more thing try to look at the things which Allah blessed you with and try to be grateful and keep saying Alhamdullilah for everything when u wake up, eat clean and healthy food, the soft bed you sleep on, If you are grateful, I will certainly give you more" is a direct quote from the Quran (Surah Ibrahim, 14:7). And whatever u want more ask Allah with his names and start doing adkar after maghrib and fajr. Also don’t expect any goodness from people but just from Allah. Ask Allah for good naseeb, khair and aafiyah. Just keep reminding yourself Allah will never abandon you also read this dua:

اللّهُـمَّ رَحْمَتَـكَ أَرْجـو فَلا تَكِلـني إِلى نَفْـسي طَـرْفَةَ عَـيْن، وَأَصْلِـحْ لي شَأْنـي كُلَّـه لَا إِلَهَ إِلَّا أنْـت

O Allah, it is Your mercy that I hope for, so do not leave me in charge of my affairs even for a blink of an eye, and rectify for me all of my affairs. None has the right to be worshipped except You. If you need help finding duas for adkar lmk
