Is this the right section? I hope so.

I just started my first semester of community college and for some reason, I've been feeling very anxious and sad...like, I have no motivation to do my work, I want to cry all the time, my chest currently feels very tight, and im dreading going back tomorrow.

Im alone the whole entire day, and I hate it. When I was in highschool, I wasn't ever invited to hang out with people, and I didnt have a group...I was a loner, but not really, if that makes sense. At the end of the day, after hanging out with people during class, laughing, having fun and socializing that way, I'd just go home. It started to bother me during my senior year, but only occasionally, since I am introverted and dont want too much interaction all of the time. Being alone with no one to talk to day after day really does suck. No one seems to be interested in making new friends since they already have an established group since high school, so I dont know what to do. Im going to look into a couple of different clubs that im interested in, but I've just been feeling so sad lately...like right now, Im trying not to cry. I just dont want to be alone for the rest of the semester, or until I transfer to another college. I wanted to form my own close group of friends, and im worried that it might not happen....any tips guys?
Im a very shy person, but im very open to making new friends...it just takes a while for me to warm up to new people.
