Thanks for letting us know what a pop is.
Changing to only one benzo would eliminate the shorter acting Temazepam which would give you a smoother taper but you don't have to do this, regardless, I believe the Temazepam needs to go first since it is the shorter acting.
I don't feel your mood will be lifted until you're off of the 2 benzo's and recovered from your use, while tapering and once off the drugs you're going to have sleep issues and withdrawal symptoms until you recover so it's important to set realistic expectations. Your symptoms will change, lessen, increase in intensity and decrease at times, you'll experience windows and waves but you're feeling all of this now so at least if you're tapering, you have hope for recovery, the way you are now, there is none.
Recovery is possible but in order to recover you have to be fully committed to this process. Its long and it's hard but its your only chance for freedom. If you stay on the drug, you'll most likely continue to be miserable, if you get off of it, you have a chance to live your best life.
