Stress at work

My job has peaks and valleys. We just encroaching our busy time and have had exta competition this year. (The person i took over for retired about 18 months ago after working with these clients for 20 years and is now working for the competion). I'm finding it incredibly stressful. I have that uneasy feeling daily and although I have loved my job I'm finding I don't want to go anymore. I know this will pass at work but with breaking my arm (requiring surgery and physio), loosing a baby and now ttc I'm just feeling like it's my breaking point.

What do you do to relax and relieve stress? I need baby friendly advice and I basically can't exercise with my arm.
