Guys.  The only advice older users can give is...just be yourself.

May be cheesy, but it works. Yeah some users may hate you...but everyone has those 'haters' and you will just make new friends eventually<3

People need to get into their heads that no one is ignored.

Not on purpose anyway, or without good reason.

Also, if you really have a problem with bullying or anything, you can send in a support ticket. lD

I used to have a real social anxiety problem--though that's probably not your issue--so I know how it feels. The thing to keep in mind is that everyone has insecurities and issues (not just you), you'll probably remember your screw-ups for longer and as more serious than anyone else remembers them, and even if you're not particularly well-liked, there's always people who'll be on your wavelength. Some places will fit you more than others.

If you don't like confrontations, just learn a few simple ways to politely leave the conversation, or just don't let them involve you in it personally. It's not for everyone.
