Hey Ashley,
Welcome! Congrats on 53 days sober - that's awesome!
Your sweet 16 can be a sweet and sober 16!
My advice? Talk to your outpatient counselor. See what her suggestions are. Can you spend your bday with other sober friends that you met in rehab? Stick close to sober people, not just on birthdays, but all the time.
Past partying friends might say that being sober means 'boring' - that is so NOT true.
You're in good company here, Ashley! Look forward to hearing about your bday plans!
