No, they don't look yellow, but Watchkeys is right - you can't get a diagnosis from us.
You'll be very unlucky if you have any permanent damage at 30. It's possible, but not likely. There is a good chance that you'll have a fatty liver, and possibly hepatitis, but both are reversible with complete abstinence.
The temptation is to stop for a while, then tell yourself that the damage will have reversed and that moderation will be fine. It probably won't if you have a taste for the booze, and before you know it you'll have permanent damage and a lot more worries besides. The best thing will be to stop altogether. That's surprisingly easy when you know that drinking will actually kill you, and not so easy when you think you can have 'just a couple now and then'. It's your call, obviously, but you'll stop one way or another, and it's better to do it when you still have a choice.
I know not everyone agrees, but I found that drinking alcohol-free wine was a huge help. The supermarket fizz isn't too bad (and is much lower in both calories and price than the real thing). If you are used to 'wine o'clock' it helps to keep the habit side of things in check until the addiction side is taken care of. I found the ritual of opening the bottle and pouring a drink into a wine glass soothing, and it did the thing of separating work time from relaxation. Others will tell you that it prolongs the agony, which is possible too, but it worked for me.
I would also suggest that you think about whether you want to change your life completely, or carry on as before but without the drinking. I went for the latter, and continued to go to the pub, or stop off at the wine bar on the way back from work. Again, it's horses for courses, but I found that it meant I wasn't missing friends and the routine of how things were before I stopped drinking, so I wasn't resentful. I just swapped wine for soda water (with ice and a slice it doesn't look like a child's drink) and after the first couple of times nobody commented. Whatever you decide, you do have the chance of a whole new life, and it will be a lot better than the one you're living now - I promise.
