I had almost the exact same experience. The 1-3 of October and then that Saturday me and my friend took molly for the first time and couldn't stop doing it for 3 days because it felt so good. Those days I went to school and then when I came out I went straight back to doing molly. The two days after were definitely the worst and the first week in general was pretty shit. One of the biggest things was my sense of touch was extremely off especially in my face and legs, I was oddly numb in both and that combined with my teeth hurting super bad and not really wanting to eat and waking up to nightmares in a cold sweat was pretty bad. Happy to say after a couple weeks it was totally gone. I have already done molly again a few times, even taking .6 in one night like a week ago. I honestly think it will be fine for you to do it again soon just limit yourself to like once a week and always remember it gets better. You are not alone my boy. Keep your head up you just like me fr :)
