You don’t recognize yourself
You stopped going to church. Stopped working out. Picked up these terrible “crazy girl” habits and isolated yourself from all your friends. A relationship shouldn’t change you to the point you don’t recognize yourself in the mirror anymore (inside and out). If you’ve fallen that far over the ledge you have surely dipped into insanity and need to come on back.
Find a healthy love this winter. Save yourself and value your own happiness and sanity above all else.
