Hey omnom if you feel like crying, go head and ball out!! It's okay, we spent so long drowning out our emotions in opiates (or any drug for that matter) and now sober these feelings need to come out! Don't feel embarrassed or guilty or ashamed.
I can also promise that if you are feelin sad or angry, after crying or screaming and punching a pillow, you will feel SO much better. Keep up the fight, I am rooting for you
