Hi @ExistentialRose,
I suppose there is a couple of different aspects to how that symptom manifested for me.
Mainly, it would come up with someone that I had a particularly intense attachment to. They would make clear statements that showed that they genuinely cared about me, and I was definitely able to believe these at the time, however by the next day or by the time we’d had another interaction (which was usually within a couple of days), I couldn’t be secure in believing that they still cared about me, as I thought they might have changed their mind since then. So basically my belief of being cared about by them could only last if I was constantly being reassured of it, and if I wasn’t, I would frequently interpret what they did in between these reassurances as ‘proof’ that they actually no longer cared about me.
In the case of pretty much everyone else that I interacted with semi-regularly, it was similar to what you’ve mentioned, in that I just assumed they were indifferent most of the time. Even when they were doing things because they cared about me, I couldn’t trust that that was the reason, as that felt like too much of an assumption to make. I’d convince myself that the more likely reason they were doing it was because they felt like they ‘had to’.
In some cases though, I would assume there was actually a negative ulterior motive behind others’ ‘caring’ actions. Like if someone complimented me, I’d think it was to make fun of me. There were even cases where I’d (incorrectly) feel like people didn’t care about me enough, but once they did show me a lot of attention, I was certain that there was no way they actually cared about me that much, and that they must be deliberately showing an excessive amount of ‘care’ to prove how ridiculous it was for me to think that what they were doing previously wasn’t enough.
I don’t know if it’s possible to ever be 100% certain that someone is doing something because they genuinely care about you, however since that period of my life where I most strongly experienced the things above, I think I’ve been able to ‘recover’ enough that I can trust when it’s the most likely reason, and that if it turns out that it isn’t then I am capable of coping with that. Though I get that that might not be super helpful/reassuring if you’re at a point where you feel that you’re not able to do that. Another thing I found beneficial was to reframe it to think that if someone close to me is putting effort into showing that they care, I would be doing them a disservice and it would be unfair to them if I were to assume they were lying or didn’t mean it.
Hopefully that's helpful, and feel free to reach out if you have any other questions 🙂
