I hate my anxiety

It feels so unfair - I was doing so well and then for a few weeks or so I wake up and every possible thing that would normally just be like "ugh" fills me with this paralysing dread and normal things take a huge amount of willpower, and when things are happening around me my mind instantly darts to the least salubrious reason or outcome and I need to sit down and do deep breathing and drink water and pray and goodness knows what else to get on anything like an even keel again.

I don't want another change of meds because I've just about oriented my lifestyle around the side effects of the ones I'm on, thank you very much.

I'm on the way to see my therapist and all I can think is that she'll come out with some platitude or say something that makes it sound like my feelings aren't valid. I really don't want to sit there and talk for an hour about how crap I feel when the propensity to feel crapper than usual just seems to come out of nowhere. I do most of what I'm 'supposed' to. I sleep (usually), I eat, I don't drink alcohol (often), I've cut my caffeine consumption a little, I stay hydrated, I do the breathing exercises, I invest time in creative hobbies, I am 'mindful' of my own feelings and sensations, and I succinctly tell my loved ones when I'm going through a rough time so that they can adjust their expectations accordingly. What else can I reasonably do except exercise, which at the weight I am just feels uncomfortable and exhausting?

God please God, can this phase be over soon and can I go back to my 'medicated normal'?
