Seeking Comfort in Allah’s Wisdom and His Plan for My Life

Assalamu alaikum. I'm writing this while sitting on my prayer mat, tears still fresh. I had been helping my niece with her English finals, but I was exhausted-last year of high school and a mountain of my own studying to do. I managed about half of her material before joining my family for a bit. It was past 6:30 pm, no coffee or anything, so I got myself a drink. Realizing how much was left, I excused myself and asked my sister to take over. My mother though, got upset, saying I was lazy for sitting around and should've asked my sister from the start. That stung because I really gave it my all. Then my sister called me sensitive, and that's what broke me. I've always been sensitive, and I've been working on myself emotionally, something my family barely knows. My brother, her father, thanked me later, which helped a little. I went to my room and just sobbed, trying to calm down. I reminded myself-I may not have a shoulder to lean on, but I have a ground to prostrate on. So I prayed two rak'ah and looked at some Islamic reminders to soothe my heart. I trust fully in Allah's plan and know He will guide me through this. Please, share your own stories of how Allah helped you in tough times-I could really use some comforting words. Jazakum Allahu khairan.
