Feeling Worn Out by Life's Challenges

Assalamu alaikum everyone, I’m struggling to put my feelings into words, but I’ll try. I’m a 30-year-old woman, married but no children yet because of some health problems I’ve been facing. I want to be honest and say I always strive to be a good person, kind to others, and there for my family and friends in any way I can-emotionally or practically. A couple of years ago, I went through a serious spinal injury that left me bedridden for months. During that time, I really needed help, but my parents and siblings, who I’ve always put first and supported endlessly, weren’t there for me like I expected. My brother and sister, both adults, actually seemed annoyed and even insulted me when I asked for assistance. Alhamdulillah, my husband did his best to help, but his work kept him away often. I ended up moving back to my parents’ house to get the care I needed, and honestly, the two house helpers there showed me more kindness and dedication than my own family did. They never complained and always made sure I was okay. It brought me close to depression, seeing how much I’ve sacrificed for my family-especially my unmarried siblings-yet receiving so little in return when I was at my lowest. I spent months crying during Tahajjud prayers, sometimes praying from bed because I couldn’t sit up. Alhamdulillah, I’m slowly recovering, but I have to admit, I’m feeling really angry at Allah right now. Over the past year, I’ve made so many duas and wishes, but it feels like nothing is coming true. It’s hard not to feel upset when I see my sister, who was often cruel and selfish towards me, now happily married and living a joyful life. The last decade has felt like one trial after another-more than some people might imagine. Just when things seemed to improve after moving away with my husband, this injury happened, forcing me back to my parents. Now, with my father showing early signs of dementia and unfairly blaming me for things, I’m stuck here waiting for a visa to move again. I feel hopeless, wondering why life seems so easy for some who aren’t kind, while I, who’ve tried to never hurt anyone, face endless struggles. Sometimes, it’s hard to even breathe. The final blow came yesterday when a good friend of my husband and his wife hosted a birthday party for their child and invited everyone except us. I’ve always welcomed them into my home, cooked for them, and been there for her. Our husbands are childhood friends, and there’s been no misunderstanding between us, yet she didn’t bother to invite me. She’s aware I’m not bedridden anymore and is happily posting about the event online, which really hurt. It feels like no matter how much I do for others, Allah hasn’t sent anyone my way who treats me with the same care. I keep losing-friendships, peace-without gaining anything back. I’m fed up and angry, but I don’t know what else to do. Sorry for the long message, and jazakum Allahu khairan for listening.
