I Seriously Need Time To Myself

Like fucking seriously, I am always running around going out, I just want a day I just stay home or do what i actually want. I just wanna fucking relax and not worry about problems, a proper study sesh would be nice too... But instead I am always running around doing shitall and I dont even gain from it...I think its best if I be selfish for now and stop thinking and caring for others. Nothing is wrong with that right?
