Advice

Hi I’ve posted on here several times but I’m 20 and I weigh like 90 pounds or so. Started taking lexapro 5mg about 2 weeks ago, going into my third week. First couple days I started I felt nauseous and what not but it went away. My anxiety also increased. Then, entering the 2nd week I felt better. But now not only do I feel my anxiety is horrible because I look up everything thinking I’m going to die, my vision is annoying, there’s certain nights I can sleep but others I can’t, I have chest pains, and I get dizzy. I’m super annoyed.
