I can so relate. Every time I am about to get a period I tend to sink into a depression and my anxiety is off the charts. The worst part of this is that I always forget that these slump periods coincide with my period cycle. So I can often ruminate and beat myself up over feeling this way for what appears to be a total symptom of PMS. I would always say to myself “my life is great, I have a job, why can’t I just be happy!!!” It wasn’t until I started tracking my cycle with an app that I realized- wow these monthly slumps MUST be hormone related. I haven’t had my period in some time due to breastfeeding but when I get it back I’m sure these symptoms and “slumps” will return. I will work to find relief and post about what helps me deal with this!
