How do I cheer up?

I'm just lonely all the time and my work schedule and taking care of my grandparents makes it hard to go out and meet people. I'm 22 and been single for 3 years now and I just want what other people have.

I want to be held by a man again and feel special. I go months without even a hug. I'm always so independent and for the most part never got sad about being lonely but it's hit me like a brick wall.

Anything to cheer me up would be appreciated. :/
