Welcome to SR Sairah, you are definitely in the right place to seek help/advice about getting sober.
Sounds like you have some pretty major health issues from your drinking, I'd echo the comments that you are likely to lose your job/health if you keep drinking anyway. And if you are in the physical condition you say you are in, people around you will know that you have a drinking problem anyway - so you might as well get help for it, right? Drinking can and will take everything away from you - including your life - if you let it.
