I can't seem to emotionally attach myself to any acquaintances and friends
Is your anxiety interfering or your fear with your relationships of all kinds?
Yeah, I am terrified to let people down.
Emotional attachments are what most of us have in our lives. Don't be afraid, just be yourself and the right people will gravitate to you and if not then that is their loss. Don't stress about it, it will make you insane.
I refuse to let these people down. They need me and I need them.
You should allow yourself to be vulnerable with your friends. It doesn't have to be all at once because that can be overwhelming but you should have someone you can confide secrets in.
