Im no professional but i would definately alert someone about your current issues straight away, if your current therapist is being unresponsive seek a second opinion as it sounds like your drinking may be affecting the natural course of the medication and could cause complications if it goes unchecked.
I feel awful for you hun

it sounds like you've been through so much and just need help getting back on your feet. I know it can take a while to get rehabilitated in the uk but i don't know where your from so im not sure if this will be a problem for you. Is it a possibility you could go into rehab? It might be something worth discussing with a health provider. If you have private health insurance then i would definately see about getting an assessment from them (some are free prior to admission) as this would probably speed up the process and may ensure better quality treatment. Have you thought about introducing yourself to the addiction forum? Others there might be able to point you in the right direction and support you. Feel free to keep talking to any us of any time and good luck finding out the true extent of your diagnosis
