I agree with lxegirl, try taking some melatonin capsules. They are OTC. Take them about 30 minutes before you plan to sleep and it should help you rest easier. If not discuss it with a doctor and seek medication to help you sleep. Also are you currently on any medication for any disorder if so that could be the cause of your irritability and annoyance with things. I too am bipolar and currently on Depakote and Abilify and it turns out that I was too low on Abilify and was experiencing those side effects. It's something to check with your doctor about.
