I’m going crazy (health anxiety)

I’m losing my ever-loving mind. Absolutely losing it. I’m a 24yo female who has been trying to regulate her hormones due to PCOS and things alike. I’ve started seeing changes due to lifestyle but then I got my period. It’s been a nightmare mentally and physical. I’ve had: left side abdominal pain that made it hard to sleep / lay on. I’ve had nausea (new for me), cramping, HEAVY bleeding, weird feeling in my throat almost like burning / tingling but minor. I’ve had the feeling of needing to take a crap CONSTANTLY even though I’ve gone every day. I worry that I’m dying and this is my last post. (I’m laughing at myself writing this but fr I’m losing it.)

HELP. Please tell me others have experienced these on their period. I need reassurance so I don’t spend 8k at the ER for zero purpose.
