Autism and OCD

I’m diagnosed autistic (low-support needs) and I have a hard time knowing if something is ocd or just a result of autism. Like.. sometimes I can be quiet and awkward around my husband’s family. I have thoughts like “they don’t care to talk to me… I don’t know what to say to them… I feel like they are the cool kids and I don’t fit into the group…” And the lines are blurring into ocd, I can tell. I just don’t know how to deal with it when there’s an element of both involved. Sometimes I wish I could just un-mask and tell them “yeah I’m awkward, I know” or “sometimes I don’t know how to talk to you all in a group when you’re all chatting back and forth so quick, my brain just doesn’t work that way.” I tend to be a slower deeper thinker. I feel like they mostly joke around and talk about sports or something they are interested in at the moment or family stuff and I never know how to chime in. Occasionally they ask me about my job or how things are going with us… I just can’t shake this feeling that some of them don’t like me or don’t care to know me. I do also have an ocd theme of feeling like I’m not worth knowing or I’m boring or people don’t like me in general. But I’m also good at pattern recognition and I can tell when someone doesn’t like me. There’s also research showing that neurotypicals can sense when you’re “different” and tend to like autistic people less. Anyways… I just don’t really know how to deal with this today. My husband is quite close with his extended family and we are around them weekly. It’s becoming more of a trigger.
