I would say, you know yourself best. If it's stressing you out, don't commute on a bike. Take it on the days you feel up to the extra effort. It sounds like your commuting on the bike to justify the purchase. Maybe in the beginning that was important?

I stopped riding for about a 1.5 year stretch because it wasn't fun anymore. I had other things in life that were going on and when I went to ride it wasn't having the usual de-stressing effect. It was the opposite. I felt like I was fighting the traffic and elements and i'd come home more fatigued. It was all mental energy. It upset me because i'd ridden for over a decade with none of these issues. What was wrong with me?? I sold my bike and said, well I guess i'm just not into it anymore. I went a year without thinking about motorcycles at all. And then the bug started again. I picked up another bike and riding has been fun again the last 7 years. I guess I just needed to get through that time in my life.
