Mood changes with & without cycles

I've had trouble with the racing thoughts, anxiety, indecisiveness, the constant urge to do something, feeling like I'm on edge with everyone, and not sleeping through the night (though I'm not tired) before my last cycle and each time it lasted for about a week. Last month, and the time before that I had got in a mood like that before my cycle had been several months before, though that time it was mainly anxiety, possibly depression, and sui thoughts. Either way, those match up with the symptoms of PMDD the last two cycles and other random ones. It also happens when it isn't anywhere near time for my cycle to. It probably happens more often not corresponding than it corresponds. Last time I brought this up to my T she asked if it was time to start my period and it wasn't and she asked if they corresponded and I told her they don't usually. She said I could still have them unrelated to period and my period just induces one of these, but it doesn't always induce them. Is it possible for weeks of moods like that unrelated to menstrual cycles, but a menstrual cycle might induce one, but doesn't always? I'm almost willing to take meds because it's so tough to control it.
