Medication is just a vessel. It's purpose is to make it easier to get to the core problems that are there. Have you been able to face them at all?

If you are still working on it and the meds are losing their effectiveness perhaps you should make an appointment with your P and look at adding or changing meds? The human body will build tolerance over time and sometimes you have to mix it up a bit. Maybe you've done that already?

Acceptance has been my personal key and has had the most impact on "getting better". That and meds But I am using them to explore and identify the anger, fear, loathing, lethargy, misplaced judgement and all that crap.
