I am starting to realize that people are a lot more approachable than they seem, sometimes it's just me and my fears that are holding me back. Most people won't judge you, also, you can always make new friends yismymindblank, if the current group of people you know have been harsh to you in the past, you can always try making new friends.

Don't feel the pressure, just saying "hi!", won't upset anyone, and it could lead to friendships. I'm struggling with people too, I just hope this helps, I have made some new friends, and it made me realize that it was me that was holding myself back to a certain extent.
