I have headache, weight gain, and altered taste with menstrual changes. Please help.

Hello doctor,

I am a 25-year-old female. I have been experiencing worsening symptoms over the past three months. I was thinking pregnancy but that was tested negative with a gynecologist and PC, two blood labs for HCG and one CBC, as well as a thyroid and hormone test.

My symptoms are: frequent headaches and shock-like pain below the right temple, migraines that last for days, dizziness even when resting in bed, weight gain, fatigue and sleep for 14 hours straight, change in taste i.e. toothpaste taste like hairspray and Kombucha tastes like hairspray, smelling burning plastic and no one else can smell it, losing balance when trying to do yoga and work, seeing shiny flex of light, pain in back, stiffness in shoulders and neck, numbness in the foot for a week, tingling in arms and fingers, painful electric shocks in the leg, mood changes crying and laughing for no reason.

Menstrual changes show shorter cycles and never before pregnant but nipples have left yellow streaks in the bra, fumbling with tools at work.

My current medications are Effexor 37.5 mg, Smarty Pants multivitamin, Vitamin B complex. I also consume daily probiotics.
