Being back at work

I’ve managed 2 days back at work so far. My job itself is good, everyone there is lovely. But it takes me 1.5 hours to get from my house to my sister’s and then to work. I don’t drive, so it’s 1.5 hours walking in the morning and again in the afternoon. I have a massive blister on my foot. Also, I got soaked on the way home yesterday, as it poured down and you can’t really hold an umbrella and push the pushchair.
While at work, I’ve been constantly checking the clock. I missed my baby immensely (although I know he’s safe and being looked after). It’s heart-breaking. I’m still dreading going back in, which I have to do tomorrow. I’m not really sure how long I can keep this up.
