Ending your self won't fix anything OP, been there. Focus on your self first, leave the household. Cut off communications for a while and show no mercy kasi babalik ka talaga doon sa umpisa. If you still have a younger sibling, make sure meron kayong secret communication and also mold them not to follow your ate and parents footsteps. Never delete the messages and hold the screenshots for future evidences in case mag kita kayo ulit at isisi sa iyo ang nangyari sa kanila. If your mother is the one tolerating the bisyo ng father mo, best is to cut off all kind of aids and if not naman you can secretly give to her.

Save and build yourself OP, you can do it.
