Hi Mancini,
I'm glad you came here and posted, and I'm sorry you are struggling right now. You are so young, and smart to stop drinking now. I would definitely look into rehab either inpatient or outpatient to help you. The detox is good for the initial few days, but you need a plan to help you stay sober after that. There are many paths to recovery, and you will need to find what is going to work best for you.
Until then, hang out here and read and post as much as you need. If you are having physical withdrawals definitely head to the ER so they can help you, and if you do that ask to see a hospital social worker, they may be able to help you navigate your insurance, and the possibilities for treatment.
You can do this.
