what is the reason people don’t like me all that much, but don’t tell me that?

that's my gut feeling and instinct. i am positive that this is the case. it hurts me so badly.

could it be because

• im introverted (?)

• i come off as desperate (how?)

• i dont show a warm or fun enough personality, or dont celebrate or give others enough attention

• i don't talk much

• i lack social skills and that makes them see me as non respectable

• other

please give me possibilities. and feel free to ask for expanding
