RSD advice
Hello everyone. I am a bit new, I've only made a proper post here once. I'm also new to discovering my own autism and ADHD so I apologize in advance for any mistakes I may make.
I am looking for any sort of advice on how to manage RSD. I know some people believe it is only a trauma response but I don't feel this is the case for me as I have been this way for as long as I can remember and I don't believe I have any significant trauma related to rejection. I was quite sheltered growing up and didn't suffer constant harassment or bullying from children at school or anything like that. (In fact I was homeschooled.)
My distressing experiences with rejection seem to be related not to the actual rejections (or perceived rejections) but my own response to them. When I feel rejected it cuts deeply and intensely and I can end up having irrational and disproportionate responses in person (like lashing out or crying) or if I'm by myself and I receive maybe a message or just a random reply to a comment I made from a stranger that makes me feel rejected I just feel this horribly crushing sense of dread and I may ruminate on it and berate myself for days or weeks after. I think to myself things like, "I'm so stupid", "I shouldn't have said anything", "no one wants to hear what I have to say", "I'm annoying", etc. I should note that what my brain clocks as "rejection" can be anything from an outright rebuke to a correction, constructive criticism, or a vaguely negative or even simply neutral comment.
It has severely impacted my self-esteem and my day-to-day life for a very long time now. Spending time with my loved ones can be difficult because the most innocuous comments to someone else clock as rejection in my brain. I fear meeting people even more than I would already because I anticipate they will dislike me no matter what. I never feel confident in myself and I never feel like anything I do is good enough, because one random person might not be perfectly happy with the things that I do and say. Even using this very platform I am constantly plagued by my extremely disproportionate reactions to certain people's responses to me. This may be devolving into a bit of a vent but I just feel it's necessary to provide adequate context as someone thought I was too vague last time and I don't want to cause confusion or ambiguity.
So, what can I do about this? Has anyone else suffered something similar? How do you handle it in your everyday life? I am particularly looking for practical strategies, not vague things like "love yourself" that don't explain how to actually go about that.
