Confused, Emotional and Depressed

So I've been having a lot of thought about my job. I work for a manufacturing company and home is quite far from my work place. I drive for almost an hour to reach work and it's tiring. A few months ago I underwent a miscarriage after being pregnant for a month. This has made me feel different about my job because I don't know if it's the work stress or the travel that affected my pregnancy. This has had a negative effect on my job and I don't feel like going to work anymore, I wake up everyday thinking of an excuse for not going to work and I pull myself through the day with great difficulty. The only reason I keep working is because I need the financial assistance to have both ends meet. Confused on whether to quit or if I need to seek professional help.
