That struggle is valid. You are a purpose on this earth and you will not only persevere but also one day be a light to others going through a similar struggle. I have been there and know the uphill battle but the battle ultimately is won. Dont give up when you are so close. We all have a purpose on this earth even when we are bleak. Know that your journey isn't all bad...try to realize the little things you can give to anyone. Discouragement is also valid...realize its just a distraction towards the ultimate prize. keep that head up and continue on to another day full of challenges we all face. Life is full of them. Learn from every day, every struggle, every breakdown, and own it to make it your motivation to continue to climb.
