I feel so so lost and confused about my life :/?

Wow you sound almost exactly like me it's scary o_o The only differences are i'm a 19 year old guy & i don't work for my mom. I'm shy, keep to myself, also could have been a loner if it wasn't for this 1 girl that i had in 3 of my classes, & her boyfriend, we would hang out at lunch sometimes, but see with me i rarely stayed at school during lunch because my parents would take me to eat somewhere, so that didn't help me socialize with other kids >.< My older sister was also pretty popular (she was 2 grades above me) probably because she's very pretty & out going. Well anyway this isn't about me but yeah i'm not sure what to tell you :( I mean you should just try getting out more or at least staying in contact with people online over the weekdays & then by the weekend hang out with them?
