Oral use - Extended Depression after Mdma use

[zilalti]

SWIM has used MDMA a fair few times but have never had a comedown lasting for more than 2 or so days. Last Saturday SWIM took roughly 250mg of MDMA powder for the first time in several months. The come down the next day was usual and the following day the same but to a lesser degree. However for the days following SWIM has been experiencing Very bad depression which is unusual for SWIM. It is getting on for over a week now and SWIM feels no better. On the odd occasion he will get a rush of energy but it will quickly fade.

This seems like an unexpectedly long after effect for such a dose and has got SWIM very worried. Is Swims worrying irrational and how long should Swim be prepared to wait before he sees a change ?

Swim thanks you in advance.
