Do you think there is any damage done or am i just paranoid?

ok so im 18, back when i was probably 15 and 16 i did ecstacy a nice few times, so between 15- 18 ive probably done a nice few ecstacy pills over 30 id say... and im pretty healthy, 115 pounds, 5'6, but i stopped doing it, i no longer will, i ended up in the hospital with severe dehydration and hooked up to ivs, and i moved on from that ****, do you think there is any damage done to my brain or heart or will i be ok? and is there any type of vitamins or anything i can take to help? i do drink sometimes too but that is all i do, and i smoke a few cigs here and there, but im trying to be healthy now and quit drugs. do you think there is any damage done i am really scared and hope not, what can i do to help myself? thanks and dont tell me im stupid, i know i shouldnt of done drugs but **** happens and i know im not being at them no more.
