CPTSD unbearable

Hi guys I’m 23 F and I am currently doing stabilisation work in therapy as they suspect I have cptsd. I have adhd and take dex but i have suddenly reduced a significant amount of smoking 🍃 for probably a few weeks and I honestly feel like im going insane. Everyone bangs on how smoking is not good for you but this is crazy, I feel terrified to send emails, reply to texts, converse with family I’ve recently completed work experience and it totally sent my nervous system in haywire. I just don’t know what’s happening to me. It doesn’t feel right. I know when doing stabilisation sessions things aren’t linear and you need to be patient but I honestly feel this doom. I’m currently putting off so many things.. I should be sending networking messages and I am finding it so difficult. Before I was so proactive at making new friends (online and meeting up with them) and idk what’s happened I just have lost motivation for everything. I don’t really cook and have no drive for that either and have been eating takeaway so much… I was considering EMDR but therapist told me to hold off due to the stabilisation sessions haven’t finished and I just feel like this waiting state is driving me insane… I suspect my mum has histrionic personality disorder so she isn’t much of help when in need things like cooking etc . She does help but when it’s her timing and it’s usually very awkward times when other things should be happening at that time. My dad is older and not that emotionally great at times and stresses me out cause of his negative outlook on things. I’m unemployed and applying for jobs so much but one application takes terribly long and I just feel like im regressing. I’ve tried to read the self help books and everything just feels so out of reach. Because of the smoking I realise it made me quite complicant with things that were wrong in friendships. Before the work experience I was meant to mend relationships and have a talk with everyone as communication is key but honestly I don’t feel like doing anything. It’s so strange I’d never thought I’d reach this point in life or ever feel like this. I have been looking into gene testing for medications and somatic therapists etc but researching is even a task for me. Is this what it feels like before it gets better? I genuinely don’t know I feel like I can’t even articulate myself properly if I was to try tell someone I know. At an age when networking is so important it feels so difficult. The worst part is I know if I felt 100% I know I’d be able to smash it out the park. I find it even hard to book gp appointments and prefer to email my concerns but don’t even know what’s going on if they will do it or not also my house is terribly cold(the windows need changing) and my parents can’t even sort it out and I don’t know if that’s a big reason to why I can’t focus as well as not having a massive room. Sorry I know this post is all over the place but whoever reads this thanks for getting to the bottom of it..
