Don't know honestly
started using at 15 then opiates at 19, addicted until current age 26 (yesterday happy bday me

I've never found the happiness while being sober like you and always start thinking I'll never be happy without opiates or I'll never be the old me and it leads to nothing good.
In your post I think it would help if you described your drug use. As in what was your Drug of choice? Was this a long addiction in which you are sober from? Like everyday use or some alcohol on the weekends here or there? Maybe some amps or an opiate addiction?
I only bring ring this up and wish you could add it into your title so people would see it and relate better to it as well, being able to respond to it because they been through exact same thing. Like I can relate if your talking opiate addiction, but I'd have no idea what to tell you if you are talking about alcoholism ha know? Maybe a mod can help you specify in title or edit your post
either way I think you have to just be able to accept what's done is done and your never going to be as happy as you once were. I mean who at 25 is as happy as they were in the young naive teen years right?
Do do you feel like you need those mess that your on? I mean I guess you really never know what you need until you wean off and aren't on them. Maybe they are doing more bad then good but idk
hopefully you you come back to check this and read this and
1) write EXACTLY what your drug use was over the years, and any addiction aspect of it
2) how long you have been on the mess are taking now? do you believe u need those mess
3) have you done any Na/aa stuff over the last 6 months
4/work or school? What's your day look like? Living situation?
I think hunk getting off the drugs is the easy part but finding happiness In life is very very difficult. I'm pretty sure that is why most people go back. But none the less 6 months is an amazing feat regardless if addicted or not.most people would give anything to be where you are and I, and I'm sure others commend you greatly for that. All I know is you are 6 months closer to happiness then most people in the drug world so keep your head up. I think maybe you wre you dieting or exercising?
I ask all these questions without much information, because there is a big difference in
A)waking up going to work, getting home, and laying in bed rest of day hating life, vs
B)wake up go to work, go walk in nature trail, shower, cook up some chicken and greens and play video games, play sports with your brother or friends, have sex, (socialize In general)
regardless you you are close, and I wish you the best if you don't see this, you are not alone and you can make it out. I'd sell my 2nd cousin on the black market to have 6 months sober like you so keeping up but instead of taking it day by day start fighting harder day by day and ull be happy in no time.
