I think i got seratonin toxicity from one time MDMA use

Okay so i have done M in my lifetime like 10-15 times only with 2-4 month breaks. But the last time i took mdma i had taken l theanine and l tyrosine supplement the previous week and i also was drunk i got all the symptoms of seratonin toxicity which went away after some time but now the anxiety and depression came back with the mdma comedown feeling every day. Did i fuck my brain or am i overthinking the effects, how are your guys experiences.
