Help me decide. Am I moderately active or lightly active?

I'm trying to set a daily caloric intake and I can't decide if I'm "lightly active"(they give the example of salesman) in my daily routine or "moderately active" (example: waitress). I'm a hairstylist, I'm on my feet 8+ hours per day but mostly only walk around the salon. However, I don't just stand. I'm cutting, doing foils, shampooing, blow-drying (I'm sure most guys won't understand this part, but round-brushing out super long/thick hair can potentially really work your arms).

I'm much more physically tired at the end of the day hairdressing then I ever was as a bartender, but I've never been a waitress either. I need some people to weigh in because its a 200/day caloric difference!

Right now I selected the lower of the 2 and I'm eating about 1400 calories per day. But I'm concerned because I also tend to hit a plateau with my weight and I don't feel like 1400 leaves me much room to drop my calories as I continue on my weight loss journey.

*Additional info: I commute to work via bike about 3 times per week (45-50 miles per week) and go to the gym. I don't factor my work outs into my caloric intake currently. I have a slow metabolism, hypo-active thyroid (yes, I'm on medication) and low human growth hormone (which I do not take medication for...but probably should, just trying to handle it naturally first).
