Have fun! Remember that you're doing this because you want to, and while it's going to be work, it should also be something you enjoy doing.
Are you wearing padding for your skating? If so, remember that falling isn't really painful. It's hard to get over that fear, but once you do you'll have more fun. If you fall, get back up and you'll probably forget all about falling - until you fall again! Just keep repeating the "get back up" part and you'll be fine.
I started speedskating when I was 32. I had only been on ice maybe 10 times in my life. I was nervous and not very well balanced at all. But I kept skating and after a month or two, I felt very comfortable on the ice. I never got GOOD at it, but I wasn't scared or nervous to go out there.
I've just started hockey at age 40. I had about 6 years in there where I didn't skate at all (pregnancy, then no time). I got on the ice a couple of times in the past year but my skates no longer fit and it wasn't fun. Now that I have well-fitting hockey skates, I'm skating twice a week. I had really forgotten how much I enjoy being on the ice. I missed that feeling of the cool air, the smell of the ice, etc.
The first time I got on the ice in my hockey skates I felt really unstable. I remembered what it was like to just step out on the ice and not think about it at all, because I was equally comfortable on land vs. ice. It only took a week or so for that feeling to come back, and now I'm seeing progress in my skating skills! You just have to remember that everyone is a beginner at some point, and the only way to get good at it is to keep practicing.
I've found hockey players to be very helpful and willing to give a n00b a lesson or two. The kids/teens...not so much, most of them have been playing for years and just want to play pick-up. But the adults - every time I've gone for stick time, someone has seen me working on something and come over to offer tips and help me practice passing, etc.
