I used to have some close flatmates with whom I dined at student hall canteens every day and had fun in the flat until midnight, but they're long gone and we're no longer in touch when they've moved on in their life.
Since then, I've always been extremely upset about not being invited to hangouts by friends with most of whom I haven't been able to create close relationship due to my lack of sociability. I've never suspected myself of any autism or social anxiety, nor have I wanted to find it out, but I've pretty bad IBS-D that makes me worry about every dish of food. I've been subject to years of abuse under different ableists, including my dad, over my condition.
I'm recently done with my postgrad and have moved in with someone I didn't know before to take a break in life. I'm subletting off from my housemate who either hosts guests in the house or hangs out until late night multiple times a week. Though we've something in common, I've been invited to join a few to none of my housemate's occasions.
When my housemate hosts guests in the house, I'd sometimes be asked if I want to participate, but I'm uninformed of 90% of these occasions, so it'd be very awkward to jump in to lads I don't know when I'm not in the mood. It also stresses me out when I want to sleep early - my bedroom is downstairs from the living room and the floor has very poor soundproof effect. My housemate has an issue of expecting me to voice concerns while getting defensive when it comes to concerns not being agreed with. I feel myself being a stranger in the house for which I pay rent when my housemate prioritises friends over me.
Now, whenever I notice my housemate having friends over or out for fun until 2~3 am, my heart simply aches. I'm having anxiety attacks more than often and slamming doors when my housemate isn't here because I'm so frustrated with myself having to go through indescribable suffering.
Having said that, is it normal to be upset about the lack of social life?
