MDMA / Extasy after effects?

Hi about 6 months ago i popped caps ( blue scion / pink playboy extasy ) , the first night i didnt mix the two kinds, i took 3 1/2 blue scions for my first time, i was very high. i didnt sleep for the next 3 days and popped 14 caps in total ( big mistake ) , i got so sick and depressed for the week after. i was wondering if it was because i had barely eaten anything during the 3-4 days i was up, and i took so many caps do you think thats why i got so sick and depressed, do you think if i popped 2 caps this friday night and dont take anymore then that i would not be so sick and depressed the following week or few days?
