I Am A 31 Year Old Female, 5'8", 261 Lbs.

I am a 31 year old female, 5'8", 261 lbs. My period is late, I have been very dizzy all day, fatigue, sometimes a little nauseous, headache, and I feel a little out of it. I take Levetiracetam 750 mg twice a day, sertraline 100 mg, and a vitamin D supplement 100 IU twice a day. I haven't been able to get my Sertraline refilled because my psychiatrist quit.
