I have adhd/ socially awkward

How are ways I can be more approachable and friendly? I feel like I may come off as stand offish/ and it’s hard for me to make friends/ acquaintances. I’m 21, and sometimes I just wish I could start a conversation with someone and not make it weird.

I’m a very loving and sweet person but my childhood and being sheltered my whole adolescence has gotten in the way of my ability to connect with others.
