Does anyone have trouble distinguishing their anxiety from normal/reasonable concern or stress? 

To sum up, I was offered a job but am not sure whether to take it bc I am having a lot of anxiety about it. Some of it is due to the job schedule which has some evenings and otherwise, I just suffered a significant loss so it’s also just bad timing personally. This job is one I think I would really enjoy but I am just not sure whether to take it. I don’t want my anxiety to run my life and spoil this opportunity but I also want to be realistic about it and not end up being so stressed and anxious after taking it. 

I have had anxiety all my adult life and feel like it’s getting worse as I get older. I can’t tell if this is “normal” nervousness about starting a new job or if my anxiety is telling me this might be too much.
