Thank you for your replies.

I doubt I have bipolar but I'm just wondering where this mania is coming from. I've heard of drugs causing schizophrenia (no evidence but some suggestion) but never bipolar. I'm just curious if an amphetamine like MDMA could be causing this. I haven't taken it in over a week so it should be out of my system, yet still I'm like this.

I don't mind it too much, I just can't sleep which inevitably sends me crashing down.
