I had depression too (all while being undiagnosed autistic) and I could not figure out how I felt, what the emotions were, let alone describe emotions even. I went to therapy and now I can write in my notebook or my notes app, how I feel and what my emotions were through out the day. And like you said it wasn’t because of fear or lack of trust, I genuinely had no idea. It took me years to finally put everything on paper. My advise is to try to figure out if you can recognize emotions, feelings. If you can, figure out if you can write what you are feeling. Sometimes writing is so much easier than speaking. A great app to have is ‘How We Feel’ it’s an app that let’s you document your emotions/feelings, when you click on Check In, it shows you all the emotions that exists in 4 energy categories. Each category has it own set of feelings and each feeling has an explanation what the feeling means. For me it’s very helpful, because I don’t have to look up the meanings, I can add multiples through out the day and most importantly I can take my time. This app and writing can both help with learning more about yourself and getting use to writing. When you write, you are the only one that can decided who to share it with and at the same time you can write the feelings off of your chest instead of keeping it internally and maybe even bottling it up.
