We all have/had obstacles and sometimes they feel surmountable and other times very difficult. During those hard times we often need to dig deep inside.
When you believe in yourself, I think, that helps you to find that place within and the strength to know that everything is going to be alright. It may not be the outcome you want but all will work out as divinely planned.
I know last year when I had some health issues, I had to look within to know and trust that my body would heal just not necessarily on my time frame!
