is it just me who doesnt like opiates?

ive had lean which didnt do anything so i dont really count it, but ive taken codeine, oxy, trams and heroin but didnt like them too much.

the only one i dont really mind is oxy but i feel so weird on opiates, they make my heart beat really fast and i dont really get any euphoria at all from them. when i did heroin i was nervous but i told myself id love it because i heard of how addicting it was, but it just made me feel panicky and i wanted it to end rather than relaxed and euphoric. ive only really had a good experience on oxy, but even then i only enjoy a low dose for the stim effect it has. whenever i took a high dose from oxy i again just felt anxious and my heart was beating fast.

does anyone else relate to this or is it just me that doesnt enjoy opiates? i have a feeling my brain doesnt react to drugs normally anymore because ive taken alot of ecstacy abusing the 3month rule, i used daily for about a month and then frequently for half a year. is it possible that all the ecstacy just fried my brain? also i understand daily use of ecstacy sounds like bs but i think my pills were cut/laced with meth or coke or something because i never lost the euphoric feeling the gave me until after around 6 months of abusing them. last few times i took it i barely got any of its magic
