Hard in to mdma comedown

i have been hard in to mdma, x and coke these last few months, just recently i have been very hard in to mdma doing about 20 to 30 bucks worth 4 times a week. I have recently tried harder more potent mdma which i am pretty sure is lased with pcp. i have hallucinated a couple times on mdma but this friday i really messed up. i blacked out and dont remember half my night i hallucinated bad i ended up stayinh up all friday worked 8am sat and went out sat night didnt end up eating or sleeping all weekend. anyway its tuesday now and im freaking out. i am having constant brain tremors or spams that happen all day and night. im a lil more paranoid i feel messed right up. why am i feeling this way will it ever go away?

i have had come downs before but nothing like this.
i am also taking anti depressants which i have not taken for 4 to 5 days (i remember coming off my last anti depressants i felt this way, so it could possibly becomign off anti depressants) tho i am seeing things differently like things that arent real i know its not real but im still sooo scared

im a 22 yr old female totally normal excpet for my lil problem which i have stopped due to my bad come down
