Welcome to the forums.
Sorry to hear that you are struggling with your anxiety and alcohol consumption as of late. May I ask have you ever received any treatment for your anxiety? Medication? Therapy? Addressing your anxiety which could be one of the main underlying issues as to why you might consume alcohol excessively? Addressing underlying issues is generally the best way to address problems that arise as a result of underlying issues left untreated.
I believe it is extremely important not to bed too hard on yourself when you do drink too much and feel the effects physically and emotionally the next day. No one is perfect and beating yourself up isn't beneficial. I think it is extremely encouraging that you are aware of your emotions and how your drinking is impacting your emotional well-being and quality of life.
I think it would be beneficial to speak to your GP and explore the possible treatment methods available to you.
It isn't easy controlling your alcohol consumption levels but addressing the underlying issues as to why you drink so much, if any, is super important.
Hope this helps.
