ANSWER - Sometimes we have to accept that our actions have consequences and as a result what we have to work with has changed. There is no quick fix to get your body and mind to the place they were in before your experience with prescription drugs and you are quite right to resist anybody willing to take your money and make you such a promise.
However the very fact that you are taking the positive step of writing for advice to get your life back on track shows that you have already turned the corner from the damage you have done to yourself in the past. You may not be able to undo the past but you can take control of your future and stop any more damage to your mind and body and in seeking help, this is what you are doing - you are taking the control back.
You say you need help and yes if you feel you need support at this difficult time then you should certainly reach out for it. But reach out to the right people and for the right help. I'm taking your comment about the "wish" as a figure of speech but in all honesty looking for a quick fix magical solution won't give you the answers you seek. It took a long time to weaken your mind and body and it will take a long time to build them back up again. Avoid the promise of the quick fix and look toward establishing long term goals you can aim for as you recover. Talk to your doctor or a counsellor who can offer professional support and care. There will be charletans on the web who'll offer you everything at the expense of your wallet but this will achieve little other than boosting their ego. The only person who can make the change and turn this around is yourself and as I said it looks to me like you have already started.
Above all, accept what you can't change. It sounds harsh but you have done this damage to yourself and you have to accept the responsibility for what you have done and acknowledge that you might be stuck with at least some of the consequences for the rest of your life. The sooner you accept this and start looking for positive ways forward the less unhappy you will make yourself dwelling on the past and how you used to be. Forget the past, forgive yourself for what you have done, take the future into your own hands and make it one worth living.
