Do you wonder about asking help from a Higher source?

I've asked God or the Higher source etc for help many many times over the years. Mainly I need help with this chronic PTSD which is severely limiting my life. But I wonder today, others have asked for help and they never got an answer and some even died in various situations. So if their prayers or wishes were not answered, how do I think mine would be or are more important? Do you wonder that sometimes?
