Comedown - I need reassurance

Hey everyone. Let me start by saying i first tried mdma when I was 19 yrs old. Did it 4 times in a span of year. After that I didnt do it for 4 years. Now since last 2 years I did it ocassionally every 3 months or so. So, 7 days ago I did it again but i went overboard with mixing as well. I did mdma, drank 3 beers. On comedown immediately i was okay, but I wanted to extend high so I drank 2 redbulls in span of 3 hours and made myself alot of coffee. Also after i drank coffee, I started drinking liquor. So i pretty much messed up alot. After like an hour when I tried to sleep I was having racing heart, dizziness, just feeling shitty. I went to ER, they checked my heart and everything and said that I will just have to ride it out. First day was brutal, I barely fell asleep. Next day I was okay-ish. On tuesday it was brutal mentally, truly suicide tuesday. Now its saturday and Im mostly okay, still feeling a bit depressed but not alot. But im scared that I will stay in this semi depressed state forever. I just want reassurance that I will get to my previous normal self. Also, Im never touching it again and considering quitting alcohol too.

Thanks in advance!
