Vent/rant

My anxiety has been spiking a lot and I'm not sure why. I just feel off, if that makes sense. I'm not in a good headspace and I really feel like shutting down, not hurting myself. I'm a woman so maybe it's a sign that my period is coming. I usually get depressed around that time but it's been hard to tell because I've been in a bad mental space for months. I think I'm just not okay. I feel anxious and nauseous.
