Losing yourself within a relationship can be crashing, soul crashing that is. You lose your worth and feels like you're nobody. It sucks to be in a situation where you know exactly what you need to do but you can't seem to let go of the "what ifs" from your past.
It may take time to really get into the program; but it helps to go cold turkey. The more you immerse yourself to going back and forth, the harder it gets in realizing your self worth. Discover yourself again. Take time to reflect what things you are really passionate about. Something you want or dream of doing soon as you wake up each morning. Take it a step at a time until you achieve it. No dream is too big if you have the passion and faith. Find your self-worth.
