Getting jealous easily.
Fear of not being good enough.
Fear of being annoying.

Fear of being to clingy.
Worrying so much you lose sleep.
Having nightmares of losing them.
Needing a constant reminder that they love you and are going to stay.
Tight hand holding.

Personal space.
It's not called being an over protective girlfriend or boyfriend. It's called having relationship anxiety.
