When Your Heart Is Too Heavy to Ask in Dua Anymore

As-salamu alaykum. I've been making salah and dua for years, but nothing in my own life seems to change. Now, after finishing my prayers, I just sit on the musallah and make dua for my family, my friends, and for all the children suffering across the Ummah. But when it's time to ask for myself... I don't know what to say. I see Allah's blessings in the lives of those around me-they are good people and they deserve it-but in my own life, things have only gotten harder. Sometimes I just sit there, tears filling my eyes, and I get up without asking for anything for myself. Maybe I'm afraid of the disappointment if my prayers seem to go unanswered again. I know I should be more grateful, and I am trying, but I'm only human. The weight of it all sometimes makes it impossible to see a brighter future. If any of you have felt this way, how did you find your way back to hope? Please share your advice.
