after effects

So for about a year and a half I abused dxm by taking either an entire box of coricidin cough and cold, or a bottle of robitussin gel caps daily, sometimes more than once a day. I finally had to stop because I got to the point where I would look at either one and vomit. I know that is fairly common, and I know feeling an abnormal heartbeat while on them is somewhat normal. But my question is, since I've been off them I've been getting sick extremely easily, I still shake from them sometimes as if I was on them, and the prescription meds my doctor prescribes for colds do not seem to do the trick(not to get high, but for their actual purpose). What kind of health damage could I have done to myself? And how soon will I really start to see/feel the effects of that damage?

I have been abusing cough syrup for the past three 3 years in small dosages every day. I don't know why I continue to do it, but I want it to stop so badly. There's no reason I do it, I just do. I don't want to die one day because of it. Anyone who has any advice could really help, it's the only thing ruining my life.

I did well for one day, how ever today I'm getting an extreme urge. I just might do it, but I hate to. Then I have to start soberness all over again, and I only lasted a day. I need to do this because I made a commitment to myself and my father. I can't let my father down,  I need to make him proud of me and happy because he's sick, and I don't know how many years he'll be around. He's the best person alive, and the closest to me. Why is this so hard for me? The image of him should be strong enough to beat this. Especially when this whole thing is so stupid. I need to continue the strength in my myself. I don't want to go to rehab. I want these thoughts to stop going through my head, they won't go away. I'm on antidepressant (wellbutrin) also. This helps, but not with this. Thanks for all the advice people have already given me, I know it's myself who has to do this, who has to keep the strength to do this. If i do do it again, I'll just feel even more guilty and upset with myself. :(
oh and by the way, the main substance I've been abusing over the past couple years is Corcedin cough and cold, and alcohol. I'm 20. I'm a young pretty girl. I know this. Its draining me.
