Overwhelmed

That does sound hard. Can you offer to bring something to the dinner with your future MIL? Then you can eat a lot of, say, your clean salad, and have a slow pace on her chicken and veg - not refusing, but she can hardly complain if you "couldn't finish" your first serving if you decline a second. Can you take your blender with you to your grandma's house? I know it's not the nicest thing to pack, but if you're driving, it's not the largest item either. And since your fiance's friends want to treat you, maybe they'd be OK with input on where to go? In any case, try to focus on the most immediate future (like today/tomorrow) to help not get overwhelmed. And it's OK to disappoint someone. Just make sure that someone is NOT YOU. People will be OK with it. They will support you. Have faith in them. Stand up for what you need and want for yourself. This is something I've been struggling with for such a long time and I finally feel like I'm starting to sometimes do right by me. You can do it!
