People often distance themselves from me as soon as they got to know me better. It's starting to bother me and I don't know what the cause is?

All my sister told me is that I'm just a weird person which doesn't help me either. I have social anxiety, I'm also introverted, I draw a line if something is bothering me but I'm nice to people. I know people on this site don't know me personally but maybe someone here has an idea what might be the cause? Does anyone else experience the same?
