Hi Jaleigh really sorry to read about your sons illnesses I have 2 kids of my own and would be so worried and stressed also in your shoes. I get the crying all night my daughter was the same and it’s hard really hard but eventually they grow past it, they say the first 6 month is the hardest.
As for the codeine addiction have you told anyone close about it ? I myself am on day 16 clean and starting to feel much better. I told my wife straight tho so that she would understand and help me thru the withdrawals, the physical side has all but gone now but I’m left with some slight depression in the form of no motivation or energy. Excercise is key and just forcing yourself to do the little things even tho you don’t want too because when it’s done you get that sense of accomplishment which is great. I’ve also used this forum and connected with others to help me thru so I’m here for you and will offer any advice I can. Feel free to ask any questions of me or even if you just wanna talk.
Get back to me and all the best you can beat your addiction just believe in yourself.
