a hang-up (about sth) (a permanent and unreasonable feeling of anxiety about a particular feature of yourself; something a person gets unusually worried about, something a person focuses on as a major problem in life, something that gives a person feelings of anxiety, something one thinks about a lot because s/he feels uncomfortable about, something that is constantly disturbing, something a person obsesses about) — пунктик, заморочка (с чем-л. или по поводу чего-л.), "тараканы"; зацикленность на чем-л.

A “hang-up” is something you’re always thinking about. It’s something that has a strong effect on you, because it’s very important. Usually, it’s a negative thing. For example, if you’re very short, you could have a “hang-up” about your height. You could be spending lots of time thinking about your height and wishing that you were taller. Or, if you’re extremely smart, you could have a “hang-up” about your intelligence. You might not want people to think you’re a nerd, so you could pretend that you don’t know things that you do actually know.
Usually, other people will think your hang-ups are stupid. They will probably tell you to get over them – because they’re probably not important. Most likely, you’re a wonderful person and you have no reason to have any hang-ups at all :-) (e-baby)
