It's not your fault Big Pharma didn't come up with **** that actually works for most people and for a long time. You are not disapointing anybody. You didn't fail. The drugs did.

It would be somethign else if you deliberatelly self-sabotaged... but not responding to the treatment is not your fault.

If you had went to restaurant and had allergic reaction to indegrient would you feel you "disappointed" them, or would it be just something that can happen?
