MDMA Brain Damage?

[saturatedlies]

Ok I bet people on here get sick of listening to this kind of stuff but last november I was really really really silly and took 1.5g of pure MDMA (over the space of about 10 hours) Since then I havent felt the same. Been having panic attacks/ anxiety/ paranoia and depersonalization. I've managed to get over the panic attacks and the depersonalization but I still don't feel quite right - like i feel normal sometimes and then other times just depressed, paranoid anxious and sort of lost. Is this neurotoxicity? Have i done permanent damage? Will I get better

Thanks. P
