lonely

ok so i’m 17 and a senior in high school. i don’t really want a relationship right now bc i want to focus on school. but at the same time i feel lonely and want a man by my side. i’ve never had a real relationship before so i don’t really know how to be in one. my point is should i just stay alone and focus on school? should i try and see if there’s something with this guy i like? what do i do? i’m just tired of being lonely but i don’t have the energy and time to be a relationship. what do i do?
