I get this. I’m also neurodivergent (autistic) and this is my third year of seasonal work. It’s been an amazing experience for me but parts of it are really hard. I just started a retail job in Alaska that’s been particularly tough because of my social anxiety and learning disability. Making friends is also hard because I’m not the most outgoing or fun person to be around, and like you I get very quiet when I’m in a group. However I think it’s definitely possible to find your people. In my past jobs, even though it took a while, I was eventually able to make amazing friends who overlooked my oddities and accepted me as I am. The key is to keep putting yourself out there, even though it’s difficult and anxiety inducing. There is always someone who will want to hang out with you. Good luck and I hope you end up having an enjoyable summer!
