hereorthere–a very prominent Torah teacher once told someone who suffered immensely in their life–“if you can find one thing to thank Hashem for every day, and focus on it for a little bit, it should help alleviate the pain of the suffering somewhat”.
Sometimes it takes years to understand what the suffering was about–until then to find something to be grateful for gives hope even in the darkest of situations. Good luck. My screen name is what I strive for–not always successfully but that’s the goal.
