Thank you for your question. I'm sorry your parents were abusive and I am sorry its been so difficult for you. Its not surprising that you are struggling with emotional issues and trying to manage what I imagine are a variety of highly intense feelings through drinking.
I'm sorry that previous attempts at therapy have felt unsuccessful. The truth is that in order for you to resolve the emotional consequences of your past abuse and your addictive tendencies, medication alone will only treat part of the problem. Please consider going to therapy and make a commitment to attend consistently for at least 6 months. Its important that you feel comfortable with the therapist so you may need to meet with a couple of therapist before you make your commitment to attend. Also, find a therapist who has experience with abuse and addictive issues. Therapy can be difficult because you as asked to talk about painful feelings which can be uncomfortable. However, if you continue to explore these uncomfortable feeling the intensity will lessen.
With regard to medicine, there are other SSRI's you can try. Similar to finding a therapist that is a good match, you may need to try different medicines and dosages that work best. Make an appointment with a psychiatrist to evaluate which medicine is right for you and your symptoms. Keep in mind that mixing alcohol with these medication is discouraged.
Again, I know feeling as you do is tough but avoiding your feelings will intensify what you are feeling while talking about them with a trained professional will eventually result in feeling better.
Good luck and best wishes.
My pleasure. If you have any follow-up questions, please do not hesitate to ask. Good luck.
