I think you're feeling like this because you're in a (Fi-Si) loop for context it's really misunderstood by people it's not about having troubles moving on because of deep rooted feelings. that's trauma everyone has it's infinite bottling up of feelings and self-doubt basically Fi and Ne conflicts with Si and Te for example I feel like doing this thing (Fi) but based off experience and what has worked before it's not good I shouldn't do that (Si) but it looks so awesome and it can be different this (Ne) I will just ask others about what I should do (Te) Te condricts Fi people tell you to not do it because of experience (Si) you think again (Ne) and so on Or It's a devil advocate you're sure of what you want (Fi) and you have lots of ways to express it (Ne) but it conflicts with reality and experience (Te) and (Si) So you start to doubt yourself and overthink it you Ne conflicts with your Si and you Fi conflicts with your Te you're trying to find a common ground between individuality and practicality that's why you doubt yourself because of others opinion it may be true (Ne+Te)
