Breaking out of my shell???

I’ve always been a loner. I never really liked talking to people. I didn’t talk much at home either. From age 15- 17 I went through depression, which made me become more isolated. I did overcome my depression but I still didn’t feel comfortable talking to people. Some would try to start a conversation and I would just awkwardly smile and turn away. I want to step out of my comfort zone but I don’t know how because I don’t know who I am lol Being by myself for so long then wanting to be this new person idk idk. I’m 19 now and I want to make friends and learn about myself, etc. Any advice on how to go about it? (Sorry if this doesn’t make sense i tried lol)
