I feel too embarrassed to tell anyone in real life but need some unbiased advice! I changed a few details for the sake of anonymity but nothing important!
Left role I'd been in for 11 years for new job that I started about a month ago. I worked out a long notice period so it wasn't a rash decision. I've taken a decent pay increase on paper- from £63k to £75k.
I absolutely hate my new job. The journey is taking a long time- I had tried it a few times and had been checking sat back every morning but the announcement to go back to the office means the journey time is now approx 1hr 35 minutes each way as opposed to the hour I anticipated meaning DD (reception) has to start breakfast club at 7am and isn't picked up until after DH finishes work at 5. I am spending the payrise on travel and childcare.
The job itself is relentless and I feel like I may be in a position to be scapegoated for some quite significant past failings in months to come.
My dilemma is that I can't afford to just quit but I'm not sure how to approach agencies after only being in the role for a month. I am in a senior role (more senior than pay would suggest but that's the sector I work in!) and leaving after a short time would definitely affect my reputation. I couldn't face going back to old employer cap in hand though have no doubt they'd take me back. I also took one of my more junior staff with me to the new role so I feel I have a responsibility to him to stay 
I'm genuinely torn between "just give it more time" to crying about the thought of having to get up and go to work tomorrow.
