I Feel terrible about myself

How are you suppose to feel when people are having a conversation with your SO and then suddenly ask why your being so quiet even though they are talking about stuff that isn't a conversation you can walk into especially if it involves a part of your husband's life you weren't in. I also don't interrupt/jump into a conversation because I feel like that's rude and that's just not me. I also feel like my husband's family/friends are use to his ex girlfriend that was outgoing/loud and she interrupted conversations (from what my husband told me. He said his ex was a loud mouth 😅 and some thought she was annoying) but I always feel like they feel weird around me because I don't talk much unless I'm talked to I stare off and just listen (I do talk though and start conversations but they usually don't take interest and they normally don't start conversations with me either) they kind of make fun of me because I don't talk much they've given me a nickname even because i smile more then i talk but I'm just trying not to be rude and interrupt conversations that dont involve me or anything. is that so wrong? So now I feel terrible because I'm not that outgoing or loud or any of that 😩 I'm quiet, calm and don't care to be around many people ive always been that way. When people ask me why im so quiet it makes me feel like crap about myself. I'm working on it and I'm trying to change. I don't know if they mean to make me feel bad but it's always said to me no matter what I do
