Feeling lost and alone.

I feel very alone.. all of the time. I am 18 I just graduated this year. I have 2 friends... but one is pregnant and busy with work about to start a family. I completely understand. The other one doesn’t get out of her house much... and I can’t get her to. I want to work on myself and become more involved in activities and hobbies.. I don’t have any kind of hobby or anything. I don’t know how to make friends either. I’m socially awkward 🤦🏽‍♀️ any advice?
