Am i alone in feeling this way

I’m 21 years old and I’m a full time student. I live at home because it saves money. Lately I’ve been feeling really down and desiring to have my own place but at the same time, I feel really really selfish and unappreciative for feeling that way because I know that many people wish they had the opportunity to stay home and save money. Idk why I just wanna have my own place. I don’t tell anyone cause I don’t wanna ever seem ungrateful. Has anyone else felt this way?
