I really agree with what @Fractal_Explorer wrote.
In addition i would say very important is a daily structure that supports nervous system regulation and serves as a safetly net when reccon hits.
I am just building that up, but it completely changed my life.
Morning ritual, get up at the same time every day. Cold shower in the morning, one hour no phone, do for e.g. 30 mins does things that i dont like to do…admin stuff…cleaning etc.
Evening ritual, go to bed when body shows signs of tiredness, listen to signals of the body also regarding food, stop overeating and food thats not good for the body. 1 hour before bed no more electronics. Maybe some yoga and a hot bath.
Getting rid of bad habbits. NOW. Getting rid of fast dopamin.
For me building the foundation is all about getting into a state of life where i continously make steps forward rather than making a step forward and the one backwards.
Having people to talk to when in a bad emotional state, so i dont do dumb choices and make steps back.
