Hi everyone. I am 21F with a diagnosis of anxiety and depression and have been on lexapro 10mg for over a year now.
I graduated from college around six months back. Last year of college triggered my anxiety so much that I had to be on meds. 
After graduation, I struggled finding a job which led to my depression. The anxiety was gone all over and it mainly was depression.
But I finally got a good-paying job aftee 6 months of trying. Today was my first day and I was beyond anxious. I had chest pain and heart palpitations. Nothing bad happened today but I felt so anxious. I am working from home now and the company is new so there are very few employees.
I just feel so anxious that something bad is going to happen in this job and that I am going to have the worst time here. I don't know why I feel this way.
I am trying to sleep now but I feel so nauseous due to the anxiety. 
I wish I wouldn't feel this way. Why do I feel like this? Why am I so worried even nothing bad has happened. I just need assurance. I don't know what to do.
