I work at a marketing/agency firm (remote) and there really shouldn't be that much work or stress compared to the horror stories I read about other agencies. My boss is kind and I only work on 2-3 clients which is nothing apparently. But I can still barely handle it. I feel like I have to basically train myself on most things (We do have a contractor to train me but it isn't always useful). I have a lot of responsibility I don't feel prepared for since it is my first job out of college and I'm the only fulltime employee so my boss relies on me to do a lot. I'm not confident in anything I do so it is all just hellish. 

Technically I'm doing the work (not well) but it comes at the cost of panic/anxiety attacks and having to work later in the day to make up for the stress/anxiety I have that prevents me from working in normal hours. I want to leave so badly but I'm afraid I'll end up somewhere worse and I don't want to abandon my boss either because I've only been here 3 months. I had a friend in a similar situation who left their job after 6 months without anything else lined up because their environment was so awful and every day I want to do the same. I feel stuck.

So I want to ask others if they know of jobs they found were better suited to their anxiety? I imagine careers where you do the same thing every day or it is appointment based (academic advisor, counselor, etc.) might be better for me, but I don't know.
