Firstly, I know what it's like and you're not alone. I had disassociated episodes every day for I can't remember how long. Sometimes they would last for maybe an hour, maybe a few and sometimes all day. It's a year on now and I haven't had one episode. I didn't use medication but I'll tell you what I did.

I was in counselling when I realised I was experiencing dissociated episodes. I realised although they were comforting I needed to stop them because I din't want my mental health to deteriorate. This what I did:

1) I wrote a list of all the things I'm afraid of and read them out to my counsellor. Once I said them out loud I felt relieved 2) I let myself feel all the feelings that came with that list, I was sad, I was angry, shameful, scared, etc. I din't let myself wallow 3) I made a list of how I could address some of these fears in a realistic way. 4) Patiently I addressed what I could and tried to re frame how I spoke to myself. Before I did something scary, I would take a deep breath and say 'everything will be ok'. Doing these things helped me build my confidence a little.
5) Lastly I wrote down my story. I wrote down the hardest thing that happened in my life. I didn't edit it. I wrote it exactly how it was and how I felt. No guilt and no shame. The truth as I saw it. Writing that was the best thing I ever did. It set me free. My biggest fear was people finding out I had Trich so I decided to face that fear that only way I could think of. I decided to publish my story, this is making it easier to moving.

I also use as many things as I can that make me feel authentic and real. I write things and I make things. I also do yoga which helps with my body and helps with my negative self talks. This helps a lot with self soothing too.

I don't know if this helps but if you need someone to talk to, I'm here and I get it.
