Period depression

So when typically when I am PMSing, I get unusually sad, irritable and depressed feeling. I cry a lot more. I understand this is normal. I also have the Mirena IUD, which may be elevating these symptoms. Has anyone else gone through this that can offer advice? Is it weird to want to talk to someone, like a therapist, even though I don’t believe I have actual depression? I just want to be happier, I’m scared whenever I feel like this it will get worse and won’t go away but it usually does. Idk I just need support from some fellow girls.
