All the problems you are worried about stem from somene other than yourself. You seem overwhelmed and I assume powerless in fixing those problems because they are not your own. You need to try and come to terms with this and focus on what you can control (your current and potential self). It sucks to say but realizing how imperfect our parents are is just part of becoming an adult and hopefully offers perspective you can use to avoid those vary problems. If work isn't an option, consider volunteer work or a hobby outside of the house. Find distance from problems outside of your control if they are hard to let go of. I hope you start to feel better, chin up
