I don’t know how to calm myself & start a new life anymore

This condition has been with me ever since i was a child, i was able to manage it subconsciously even during Uni which was a miracle i graduated as i always found it near impossible to revise or study without assistance of others. Ever since moving out out home due to wanting to get away from a toxic South Asian culture & finding a job , my condition had been worsening each and every year solely down to not having enough cash/income to support myself, ever since going to uni back in 2017 i feel like ive been in a constant survival mode for nearly 10 years, i did my best to enjoy life but one mistake after another financially as i never had the ability to think stress under constant pressure led to eventual burnout nearly 2 years ago but i had no choice but to keep my corporate job as i had to pay rent & debt as well as other bills. I did my best to find other income on the side using all my spare time but this made things worse and i lost any sense or ability to focus and pay attention to work which landed me in lots of trouble with corporate HR/Management. I knew i needed treatment, tried talking therapy & CBT but neither helped as my mind was already overloaded and couldn’t process anymore information. I knew i needed to get diagnosed and treated but NHS waiting lists were 6 months so under desperation i paid for private assessments and titration once i got diagnosed. When starting the treatment i realised i had to leave my flat & corporate job so i can start fresh and find myself again. Ive done that and moved into my grandfather’s house which is empty but close to my family unfinished. Since being here ive had maybe one week where i am able to focus & research what i want to do , ive always had ideas i wanted to try but couldn’t find the space to dig into it. One setback however can throw all my progress down the and i am struggling for weeks to get my mind straight. It can be one small thing like a family argument, issues with old landlords, friends , etc. I am really struggling to find a way to cope in this economy as i already walk, exercising & eat clearly but these are no helping or distracting me. I can’t afford therapy as i have no income or any support, applied through IAPT which has a minimum of 14 weeks wait. I am really struggling to find a way to ignore everything around me and focus on what i have to do to start fresh and make a better life for myself.
