Hang in there. You can do it. you are doing it.
I can feel lonely in a big crowd.
I have learned to be more open to those people who do come around me. I've also learned by ME not being open, for whatever reason, I lost a lot of opportunities to be close to a lot of people. So now I know this, and I try to hug as much as I can.
If they mean anything to you, they're worth a hug.
...it's kind of catching. Now they expect it. I had to take that initative, though. I even hug the ones that act like they don't hug. Now they look forward to a hug more than anyone.
If you can find a positive thought, savor that for a long time. Recall it as often as you can.
Think...think... positive.

may you find laughter in your day.
