While navagating your way through this crazy storm there will never be a shortage of people telling you....
"forget it, move on."
"this isn't right, you deserve better."
"this isn't fair." (I hate that word btw, unless it's associated with corndogs and cotton candy)
...those people will always be there. Are they bad people? Absolutely not. Does that make them wrong? Not really.
It's actually a very "safe" view to have considering the difficulty of all this and the pisss poor odds. It's a fairly easy or safe position to take to say, "see I told you so."
The ego is a pretty powerful thing.
This is your life, it's your choice. You live it. You decide how much you want to give or sacrifice. You decide who you are or who you desire to be.
My only suggestion to you as you make your way through all of this is to do it for you. Learn, grow, become better so you will be able to look back at all of this and be proud of how you handle yourself.
It pushes you to your limits and beyond but in the end you reap the rewards regardless of the outcome.
