Maybe because we are rewiring parts of our brain/thinking? I am going through a very similar process at the moment and somedays are better than others, but my responses and and affects of triggers are changing.

I'm always fatigued. Need illicit drugs just to get out of bed. I think its the depression/adhd/gad/ptsd combo for me

Yes I have delt with being tired a lot after I have delt with a lot of my trauma and stuff.. the act for me worked very well and I still do it (I got myself flash cards) and I am exhausted after I do therapy for it or even the flash cards .. it takes a lot of energy out of me to deal with the emotions that come with the therapy and I crash after ... Not sure if that is what you are going through.. but I was told it will get better (the tiredness) ND honestly for me it has but it took time ... I would put so much energy into the emotions of feeling what I was doing in the act therapy that after I just crashed if that makes sense .. I think I repeated myself... Be easy on yourself please and know that all the work you are putting in will be worth it and it takes a lot of energy to heal! Please remember that no matter what you are doing amazing

I defo relate to this. Once I started processing my trauma I became VERY fatigued and general depression symptoms like lack of motivation. I think it's because you're processessing a lot of repressed emotions (often sadness), and in a way can also be a grieving process (esp if you lost relationships/your childhood to trauma). I, personally, also struggle to manage this but Im just trying to give myself that space and time to heal as it is necessary. I've tried to lower my self-expectations during this time and realised that it's okay. Focus on simple things while you heal and do what you can. Do low energy activities like stretching, meditation, walks outside. Try and move your body as much as you can, some days are like that. 💕
