Worried about going abroad because of leaving my dog

I was wondering if I’m the only one who doesn’t go abroad as they find it really difficult/ stressful to leave their dog behind. ?
My dog is a needy creature by nature,( cavalier King Charles)
more so since our other dog died. She won’t let anyone else walk her and when my husband has tried, she managed to pull away from him and ran home frantically looking for me.
Also, I suffer with anxiety and so she’s like an unofficial emotional support dog for me.
Subsequently we usually rent a holiday place in the U.K. on the rare occasions we so go away

The only thing is , I’m about to have a big dilemma! My daughter and SIL are expecting a baby via a surrogate after years of wanting a child and rounds of IVF etc. She will be having to stay abroad for around three months from early November to January, after their baby is born to await paperwork.

Soo, I either don’t see my grandchild for about the first 3 months or I find a way to leave the dog for.a couple of weeks so I can fly out.

I’ve looked into flying with my dog but it’s a long journey with a stop over and the dogs over the weight limit even if I Couid find an airline that allows dogs in the cabin. (She Wouid be way too anxious to go into a crate in the hold !! )
I know it sounds stupid but the thought of leaving my best furry friend behind is making me feel sick with worry.
I’m hoping other pet lovers will understand.
We live in a nice house in very popular Cotswold village so I guess it would be possible to find someone to come and look after her but what if the persons goes out out all the time and leaves her alone or is a secret psycho !

I didn’t sleep last night for worrying about it What’s wrong with me? My husband says it’s not normal to worry about them to the extend you don’t want to go away without them.
Any sage words Would be very much appreciated!
