Craving a relationship

Hey girls!

So I know how lame this sounds but please hear me out, your advice would also be much appreciated!

I’m 16 and have never been in a relationship. I’m not sure whether I crave a relationship or just more affection I guess? I have never been close with my parents or siblings, and I have close friends but I really struggle opening up! I really enjoy when I hug my friends but I’m too socially awkward to initiate hugs whatnot. I really crave more physically love and attention, even just hugs from friends, and also more emotional support. Just one person that is always there for me. I don’t really allow myself to do this to my friends because I am so so worried I’ll burden them and i might just push them all away. Help!
