Should I go to the hospital? I'm in my mid 20s F with anxiety. 

This is the first time I feel worse. My chest hurts more. I think my heart is beating fast or slow idk. I checked my blood pressure twice in 5 hours. First time it was at 98/69 and the pulse was at 62. Second time it was at 90/60 and pulse was at 70. I think the pulse is fine but the pressure isn't? I'm getting tempted to check it again. I don't really have an appetite these days and my weight is going down. Slowly tho. I'm at 113.5 lbs/51.5kg which is a healthy weight for my height. I also feel even more tired and sleepy. I don't have the energy to even speak. My period is late by more than 3 weeks. I hate taking birth control pills cause they do more harm than good on me. I also feel nauseous and I want to cry but I can't. Like where are the tears when I need them... 

I'm scared that I might keep losing weight and have less blood. I also don't want to go to the hospital or anywhere. I don't have the strength in me. I was scared to even type this out but the blood pressure is freaking me out even more rn.
