Kjell you are right where i was when i did my step 4...not a nice time at all, doing 30 mins writing then leaving it for 2 days then back again...after doing the first piece of writing i said to myself im not doing this in my flat, it was that painful, and found a quiet cafe nearby and finished the step 4 over the next week or so...i must have seen my sponsor at least 4 times whilst doing step 4, it took me 2 meetings with him to understand what he meant by the most important piece is your part in it, i.e. the fourth column...doing step 4 was far 'worse', for me, than doing the amends but the relief i got in step 5 was indescribable and to finally see myself as i was...well it was eye opening and almost life someone explaining a riddle that i spent all my life trying to understand...
You are right where you need to be, and yeah you gonna feel all sorts of stuff and a lot of it is not going to sit well but i promise you it is worth it:-)
Yeah i think probably leave taking up a new hobby on the backburner for now!
