“I firmly believe that ACI is why my son is still alive, back with our family, and back to school. As a mother my primary concern was that my son would receive compassionate care and the attention he needed to focus on his recovery. We have been through this before and I was losing hope, so was my son. It is a very lonely and dark place to be. All ACI staff, doctors, nurses, and counselors were always available when I had questions. We were able to visit and we had a family therapy session where I learned that I had to take care of myself too, without feelings of guilt. We also learned how to set limits and boundaries. At last, freedom, from the emotional pain of being part of an addicted family. My son learned the skills he needs to sustain his sobriety. He learned about the importance of maintaining sober friends and activities. He learned how to say no and change the things in his life that kept holding him back from happiness, health, and success. Thank you ACI I have my son back!”
