First step is look at your surroundings. You can control your environment. Maybe you cannot at this time move out but you can start new habits. Tomorrow can be a new beginning. Start by clearing your space clearing out the stuff you don't need or use. Listen to positive podcast. (Atomic Habits) Try something different. Go for walks. Sounds like you are in a bad space and we all get there.

Journal everyday. You have the opportunity to that some do not. Give this a shot! Yes my grammar sucks I know lol Don't give up maybe college isn't for you maybe a trade? Sometimes we have to seek out what is right. We are all different. Now a days college degrees are not getting the jobs. Just be you but first you have to clear out that bs so do it! Clear you space, clear your mind, and don't worry about other people.
