Looking for advice on shadow work

In a few days I will leave for a 2-3 weeks vacation.

I live in a big city so I'm thinking of a solo countryside retreat. Chosen a remote little town in a valley by the river. No phone. No laptop. Just a couple books, a journal (and some acid) and the bare essentials in a backpack.

I have a few goals in mind:

1. Heal from trauma stored in the body

2. Overcome all my addictions (smartphone, smoking and all kinds of drugs)

3. Create harmony within my psyche so that there's no internal conflict

4. Be more active & improve my posture

Looking for advice/tips on how to navigate and whether or not to make a game plan
