Well, if you have to promise to take your meds like you you are suppose to, I think you might have bigger issues to deal with here. Getting your T to trust you is pretty important. Strict adherence to your meds is another. It seems like he is willing to help you and given the last two months of posts you have made, I'd really encourage you to not make any excuses and tell him everything as soon as humanly possible. Your judgment hasn't been great and by the time you think you can trust him...who knows what further problems will have happened.

If you were on the same meds for a few months and stable for a few months and living in the same spot for a few months, I'd say take your time and build the trust. But...that is not your situation. Take the help you have now and waste no time in spilling your guts. That's of course if you want help making changes that just might work.
