There is a saying that is one of my mantras in life. It goes: "This too shall pass." I know it sounds so simple but it honestly really is that straight forward and honest... Whatever you are currently going through right now WILL eventually pass! No matter how horrible and enormous and depressing your situation appears, it will NOT last forever. You just have to make sure you get through it!
In a couple of months or even weeks you are going to look back and laugh at your current situation and circumstances. What may seem so challenging right now is soon going to become a distant memory. Don't over-stress and over-think things too much. Just breathe through it and keep moving forward!
