It does get better. Much better. The antabuse may be making you feel bad.
I've never taken it but my life is so much better now it's unbelieveable. I love every new day. And I was a chronic drunk.
You can do it. Think how drinking made you feel, and if you're tempted, think that first drink through to the end. All your hard work will disolve and the misery will return.
Maybe find a support group so you can be with others who understand.
Don't pick up that first drink! And best to you, I hope you feel better soon.
