it wont be easy. you will need to have lot of patience and self control, and this withdrawal will be difficult too. you will need to eat only healthy food- no nicotine,alcohol,caffeine,milk chocolate,drugs(i am avoiding all these things for a year now)
and in your case you will continue to have episode unless you do something about your sleeping schedule. you will need to have 8 hours sleep from lets say 10 p.m. to 6 a.m. and i know how difficult it is (everyday i sleep at 6 a.m. for more than week now

) if you cant do all this better give up and start taking meds...
but i am wondering does your opinion matter that much ? i thought your dad's opinion was more important than yours
