bipolar mania onset

I was diagnosed bipolar1 5 years ago (though probably had it for many years before that untreated) and am really commited to being more stable these days. I also have CPTSD with depression and anxiety being chronic problems. I use meds, CBT and mindfulness techniques as well as trying to keep my diet healthy and have a good sleep routine ..............BUT........ I have not been able to get to the point where I can prevent the onset of hypomania and it doesn't take long for that to escalate into mania or worse (psychosis in the past) and I can stay hyperactive and sleep deprived for many weeks before it passes. It is beginning again at the moment (over the last few days) and I have a wait before I can see my psychiatrist and have my meds adjusted. I'd really appreciate some support and any advice people may have.
