I'm a rapid cycler/mixed state all the time. I actually don't really know what it's like to be on one pole or the other. -- Not purely at least.
Obviously mixed states are the two pushed together in some form, but there are quite a few cocktails. So I'll just tell you what I've found to help me?
The first important thing, and I cannot stress this enough, is sleep. Get it. Get on sleeping meds, melatonin, some kind of sleep aid. It breaks up my rapid cycle. I can cycle round about 3 times a day, but my cycle usually follows a pattern once a day. Also, it doesn't have to be at night or on a normal schedule. When you feel tired -- and it will probably hit you at weird times? Take a nap. It's weird how much it helps. But it's super important that you sleep when you feel tired and that when you feel yourself start to go up -- if it's at night -- to get sleep aid and get to bed.
Which sucks, it's the last thing I want to do.
Are the suicidal thoughts like...a mantra in your head? More like a compulsive thought? Or do they come solely from a shame/ depressed cycle?
Haha, about the poster...My husband calls this "getting past the barrier". When something gets past my barrier, so to speak, I cannot let it go, and I become obsessive over it. I am far from OCD.
Watch yourself when you can't say no. Ask yourself when you want something if you could say no. If you can't it's a huge red flag in a Mixed State ( I guess I don't know if it is in other states, but it's HUGE for me).
If you have someone you trust, have them sort of keep tabs on you.
As far as doctors, I've found that for me, it always seems to be a certain lingo you have to use to get them to pay attention to you. Even the best of them. Many of them are reticent in believing in rapid cycling or mixed, at least around here... so that may be one barrier you are running into.
I hope this helps?
