Hi, I think looking to the unknown future is scary for a young person. You are now on your own and what you do is up to you. You are looking at others as having an ideal life while yours seems to be blah for you. If you were looking in the reality of things, many of your peers are struggling also, with their own doubts and trepidations about their futures.

Try experimenting some and say "Hello" to other kids on the campus. Social anxiety can be seen as being a snob by some. Smile and make yourself approachable. I think making friends where you are is in your realm of availibility if you put yourself out there some. College is where people make life-long friends; and I hope that you stay in college and pursue your studies. Don't mope for the "good ole days", when the world can open up for you right now. Consider it an adventure in life...
hugs, bj
