Am I Pms-ing or do I have a panic attack going on?

I’ll just randomly start feeling down and then within a short about of time I start getting/anxious/panic (as if I’m loosing control), then I get angry, depressed, cry hysterically, scream, can’t control how I feel and just cry cause I’m sad I’m feeling this way and angry cause I’m frustrated I’m feeling this and can’t help myself. What is this that I’m experiencing? It usually happens like a week or two before my period so I’m wondering if it’s pms but I do have anxiety throughout the month too on a regular basis so I don’t know if it’s stemming from that, or could it be a totally different mental health problem? What am I experiencing? Has anyone else experienced these symptoms or know anyone who has?
