Sorry to hear you are feeling a bit down. I think with the food it comes down to perseverance, but you already know that.
I would mention all these concerns to the SLT. I'm sure she would get a Dr to look at you if you press it Maureen - especially for some additional pain meds. There really is no need to be in pain or uncomfortable.
Actually I'm sure the Dentists could prescribe too.
Hope you feel better today and that all goes well - especially with the travel across town.
