I am so very sorry about your husband. I send my deepest sympathy for your loss.
Sheba sounds like a very sensitive girl. She was grieving for her dad similar to how humans react when they lose someone.
You are correct that cats HATE change, however, they can tolerate it as long as the human they love and trust is nearby.
If Sheba knows the sitter and feels comfortable with her/him she can tolerate a ten day separation. If the sitter is a total stranger it will be difficult for her to accept that person. In that case it would be better to take her with you.
If you will be moving there eventually she will have to adjust to a new house. But as long as YOU are there and you bring things with her scent on them she will acclimate just fine. When I move with my cats, I use a small paint roller (the size they use to paint trim). I roll it on her paws and neck where there are scent glands. Then I rub it on window sills, furniture and new things around the house to transfer her scent onto things. When she can smell herself on items she feels safe and at home.
If you choose to leave her at home with a sitter have that person come over a few times while you are still home so Sheba gets used to that person feeding her.
