Have you been to the doctors about depression? I’m sure you have, but may be worth going again, not sure what kind of codeine you are taking, but maybe we are in similar positions.
Iv struggles all my life with anxiety more than depression, mainly social anxiety which completely goes against my personality, it has held me back so much in life, I’m 32 and already regretting all the things I haven’t done, I used codeine and the sense of not caring and just being calm grabbed me. Been 2 years now on and off, having to take ridiculous amounts to even feel normal, I hope you can get some help before you stuck on it, I can’t last a few hours without any, also have 3 young kids, it’s a hard one for me, because when I have codeine it makes me feel good, and I can do anything, but mow without it I’m useless, I feel so guilty aswell, hopefully I can get off this, not much of a good answer for you, just hope you can pull through and not let it get any further the guilt will get worse, concentrate on your son and your business, you have a lot going for you! I keep my fingers crossed for you. If you can stop taking it, please do. ????
