I am an introvert

I usually struggle to fit in, I’m not outgoing and bubbly like most people seem to be. When I started my new job I didn’t really need to try, there’s not many people that work here and I got along with everyone from day one, it felt natural and I enjoy being here. Now apparently someone has stolen money from a woman’s purse, and I’m worried people will think it’s me as I’m the “new guy”. Feels like I’m back to square one, it’s impossible to prove my innocence even though I’m not being accused. I’ve worked really hard, not missed a day, even come in while I was really ill because I wanted to show I’m committed and now it could all be for nothing. Or I’m overthinking it. This is why I hate being around people, too many variables.
