Allah Is Not Answering Your Du'ah

We cry to Allah for things we don't know whether they're good for us or not. And that's why in the du'ah of Isthahara you are asking Allah saying, Oh Allah, if this is good for me make it easy for me and give it to me. So yes, perhaps your date of death might not change but inside of that there is a lot that can be manoeuvred through your du'ah and through your charity. Keep being good, doing good, keep calling out to Allah be charitable. Even your expression on your face is a charity, ma'a shala.
