I’m 18 and have family problems, my friend mom offered me a room in her house to live in. Should I go or what?

Weigh the good and the bad. Ask yourself, will living in this situation bring you up overall or down overall? It is okay to make the right decision for you. Are there compromises available, boundaries you can put in place? What would your problematic family agree to, if anything? What other options do you have, be creative as it's possible you have more options than you can see right now. Your quality of life and your mental health are important. If they will be impact in such a way that you will be consistently suffering, you may want to reconsider your options. However, if you feel that this is a good opportunity for you in other ways, that is certainly okay too. You know your situation the best. Follow your gut.

Consider carefully how your current household is making you feel. What kind of problems are they? Family pressure? Do they bring you down? Do they physically or mentally abuse you? Do you feel absolutely miserable staying with them? What do you truly feel? Think on that carefully before making any decisions. Your well-being is important of course. It's your choice if you want to move out or not, especially when your friend's mom is offering a place for you. You have somewhere to go. This is a choice only you can make because only you know what will work best for you.
