Help me out please

I’ve been drinking every night for about 3 weeks. About 85/15 seltzers and vodka. The anxiety now every day is so fucking bad and I already have bad anxiety and take klonopin for it but it’s not touching it. I just keep feeling like I need to taper down. I cannot afford to see a doctor and am going through a very recent separation/divorce. I’m struggling. It used to be fine during the day but driving also gives me a lot of anxiety and today I had to drive about an hours worth and my mind kept telling me “you’re gonna have a seizure. You’re gonna have a stroke. You’re gonna just instantly die with your kid in the car”. It was a nightmare. I just want some relief. Last night I had 5 drinks instead of the usual 8-9 and planned tonight to have 5 again but zero vodka this time, just seltzers. Can someone tell me if because I already have anxiety, that is very much health-based, that I’m working myself up. Or what to do.. For reference, I’m 130lbs, 31f.
