I know we cannot diagnose here but it does not sound like DID at all to me, but rather side effects from hard drug use and psychiatric drug withdrawal. DID is something that only develops in very early childhood, not out of the blue in adulthood. I know it can be reassuring to look for that label that explains your problems, but this isn't the one.

As RubyRae said, take your meds as prescribed and stay away from hard drugs.
