In-laws are visiting and I'm struggling

Assalamualaikum. For context: my husband moved abroad a year ago and I joined him two months ago. His mother and sister are visiting us now, and I’m really uncomfortable having them in our space. I know some might say I’m the problem, but I’m not. I lived with them for three years after marriage and one of those years my husband wasn’t at home. Those three years were very difficult for me. We weren’t allowed to go anywhere without permission, and whenever we asked my sister‑in‑law would create issues and then stop talking to us. The only times we travelled were with her; afterwards we couldn’t go anywhere because of her behaviour. My mother‑in‑law always favored her and relied on her for everything, which caused a lot of tension between my husband and me. She once argued with me for going out with my husband and spoke ill of my parents. I reached a breaking point and reacted, but my father‑ and mother‑in‑law painted me as the problem and I ended up cutting off contact. My husband tried to reason and keep the peace, but they kept blaming me- even suggesting I’d done something to influence him- and would stop speaking to him too. Despite all that, they expected me to handle many chores, including tasks that belonged to my sister‑in‑law. I set some boundaries like only interacting when necessary and refusing certain tasks, but the home remained toxic. Fed up, my husband decided to move overseas and I followed, but now they’re here and I’m not okay with it. They’ve taken over things, and no matter how polite they act I can’t forget how differently they treated my husband when he earned less and all the trauma I went through living with them. I’m really stressed and feel powerless since they are his family as well. It’s only been a few days but their behaviour feels insincere- and even if it is sincere, the past hurts are hard to let go. I don’t want to seem cold; I want to be respectful while they’re here, but it’s proving very difficult. I’ve been skipping meals to avoid interacting. How should I handle this? Any advice would be appreciated. JazakAllah khair.
