Some good advice and some bad on here, I first started my Opiate habit at 15 and now I'm 32 yrs old and still battling my addition, and without me frightening you I can honestly say that now it feels as though its to late although i know deep down its not.
Never give in, try your best as always, also by the sounds of things your parents are opiate addicted also so coming clean to them would be the best way in my book.It depends on how they are, going through something like this on your own is no fun at all,and I no its not going to be easy to come clean I just hope U can go to them for the support, hence becoming a member on Bluelight and getting the correct support from your family and peers.
Just remember realistic goals are possible but unfortunately miracles aren't, so I would try my best at tapering down to the point were U feel in control again without getting sick,.Speaking and getting support is optional,I no a problem shared is a problem halfed and I know my parents were,and still are very much against drugs and most probably the reason I'm still a pay day user (whilst on a methadone script) is due to their ignorance and me never getting the responses for my cry's for help.
Like someone said if your folks are good enough , and by the sounds of things if there on Opiate/opioid medication then they have to give u the support u need, were as mine are totally against, and blissfully ignorant.Just remember also to try keep active so that your mind is taken off taking |Opiates, find a new hobby if possible, eat well, and excersize I'm a great believer in exercising, it releases good endorphins and will help your recovery.
I understand U can only do these kind of things if on a taper, or on a still good amount, but full blown WD, by your self I wouldn't advise, because it could put U off all together from becoming clean, and can be very disturbing physically and mentally without the right help.
Also its about changing old behaviours, and replacing them with new ones, it all sounds easy but I know it feels almost impossible.Just remember to keep strong, and optimistic, I hope U dont follow the same path as me, I'm on Methadone, and still use today when I have the money , I find the cash is my biggest trigger and I realise that you are not on street drugs which will also be a good start,Find new friends, were as I am a loner due to my drug addiction, users in the past have been far from real friends so I choose to stay well clear.
I hope your family will stand by U,I also dont recommend U swapping over to another substances either because it will still cause U problems ie, Cannabis, I found that Cannabis still left me with alot of mental problems and it enhanced whatever I was going through after smoking it for 15 yrs plus, so just try taper with support, its about being in control if possible and I know how hard it is.People say its harmless Cannabis alone, and for some ppl it is, but everyone is different, and it didn't help me as much as I wanted it to, now I'm just a part smoker of Cannabis, or on special occasions, using it daily definitely caused me more harm than good, were as some ppl it will work wonders just my thoughts all the best, I hope things work out, and remember be strong, and its about taking small reaslistic steps at a time, its a marathon and not a sprint.
