Irritability and agitation mixed with tearfulness/depression sounds like a mixed episode to me. It may subside after the company leaves and you get some good sleep. I had a mixed episode for 3 months last year

and I had to start on Lithium for the first time in over 8 years since diagnosis. If you continue to feel this way, you may have to talk with p-doc about tweaking meds, that is if you are taking meds. I hope things work out for you and you feel better soon - soft
