Whenever you face a situation or challenge that you did not expect it can be tough. When you are watching loved ones go through trials and hardships that can be even harder, because of the powerlessness you feel to be able to help them.
It can be extremely difficult at the time, but just remember that these trials are building your character muscles, they are building patience and maturity in you and those you love.
Not only will God grant you the strength to endure and overcome, He is giving you a testimony to share with others. Just know that you have faced situations that other people would not have survived, and you may meet someone who is facing your same challenge that desperately needs to hear your testimony!
So hang in there! You will overcome every battle and every defeat with victory.
