As time goes by you will learn that the people you trusted the most are the first ones to betray you. That when you are in need, those whom you least expect will come thru, become your pillars and will give you strength to continue moving forward.
However never be afraid to trust, this process repeats itself over and over, you will learn which bridges to burn and which to keep.
You are stronger already because you know who you are and what you are worth, they don't know what they are losing.
