I’d really think carefully about this (speaking from personal experience). Were you happy when you lived back home when you were younger? Do you think it would impact your mental health or self esteem? Do you think you’d be embarrassed to have friends or a hook up over? Would you still be able to see your friends and all the other aspects of your life easily? Is the money saved worth losing the lifestyle you are living? I found I saved money but my mental health dipped so much I wasted it on stupid things to cope. I’m sure most people don’t have this happen, but it did to me. 2 years is a long time! Maybe you could do like a month trial run and see how it is while keeping your apartment
