How do I scape reassurance seeking, like constantly looking for certainty or an answer

It's really good that you asked. What does it feel like before you look for reassurance? Often it can be a combination of fear, guilt, dread and panic. When you're feeling that urge to reassurance seek, you're looking to get rid of those feelings. They feel unacceptable to you because they seem to have a lot of meanings attached- lots of consequences and doom which feel very personal, and those meanings cause you to want to reject them so as not to accept them or allow them to be "real". To stop doing our compulsions, we need to work on separating those feelings from the meanings we have given them, and improve our ability to handle those feelings. And I promise you, you can handle those feelings. Once you learn that, you stop needing to get rid of them. A good start to is to label those emotions. Try googling an emotions list to find one with a lot of good, nuanced words on it, to help you really be able to identify those emotions. A lot of different things can cause the emotions that you're feeling, for all of us, so try listing the emotions rather than going over the meanings they seem to have for you. What emotions really boil down to is a physical feeling component, and a meanings component. If we focus on the physical feeling part, by labelling the emotion and then noticing and accepting it in our body, we can process it. The only way out is through, but you can do it. Try to come out of the mental meanings and notice where the feelings are in your body, and what they're like. Is there heaviness or squeezing? Where is that in your body? Try to zoom in on it. Maybe there's some aching, even sharp zaps, but you can stay in the body, focusing on those physical feelings and letting them be there. When your mind attaches meanings or tells you that you need to resist the feelings, just stay in the body. You can cope with them. Take deep breaths. This is emotional processing. By letting the phsycial happen in our body and being attentive to it rather than judging it, we process the sensations rather than resisting them. You can survive anything which happens in your body. Some emotions like anxiety are physiologically identical to excitement, it's only when we go into the head that there is any difference. All feelings can be and deserve to be felt, and you can survive them. Doing this breaks the link between emotional discomfort and meaning/compulsions. As feelings are processed in your body by zooming and leaning into them rather than looking to escape them, they gradually begin go away. You digest them. Doing this gets easier over time, you've been resisting your discomfort for a long time so you'll have a bit of a backlog. But you can do it.
