At my worst yes when my stress hit an all time high I would have very quick rapid cycles with mixed episodes. During that time my highs would last from 4-5 days and then crash into a awful low for 2-5 days and it contained for about a month. Other than that my highs last about 2 weeks to a month or two and depressions can last weeks to months always with mixed symptoms. Hope your well and not experiencing anything bad.
