If it’s a mixed episode seek help immediately. They can get dangerous fast and are different to pure mania or depression. Anyone who has experienced a severe mixed episode knows going it alone with only, even the best, coping skills will know that they are unable to reign in a true severe mixed episode. It’s great you can see it might be coming on. I would get to a T and/or pdoc ASAP as it may be able to be shut down before it gets nasty.
