feeling ashamed

So as im looking thru fb posts, pics & videos i start feeling like im never gonna be someone in life because i see my friends going to college, having fun or even i have an aunt who is in college & doing her best to become a very important person. & i feel that because I have 2 kids at the age of 21, (graduated from high school ) im never gonna achieve anything in life 😕.. Idk what to do with my life, my SO works 2 jobs & i spend everyday with the kids, i feel like it shouldnt be like this. Im interested in makeup but i feel like if i go into a career of cosmetology theres not gonna be a future because everybody is getting good at it.. I feel like i want to become a teacher, a student counselor but i still feel like its not enough. I want to achieve big goals but idont how to or if im capable of doing so...
