I wouldn't exactly call it a cake walk - depending on what kind of cake you're used to, I guess! It is major surgery - but I can tell you, it wasn't nearly as bad as I had imagined brain surgery to be! I didn't have any pain afterwards and am able to deal with the other inconveniences pretty well.
I have right side deafness and some slowly resolving facial paralysis. I've had surgery to minimize the damage to my eye that won't close and to make it more comfortable and surgery to put in a BAHA implant. These things have made my day to day life a little different, but after a year (next Wednesday) of dealing with them, I kinda just have become used to it now. I realize there are people out there suffering a lot more than I am, so I just do what I need to do.
As far as returning to regular activities, everyone is different, so it's hard to say. I basically took 2 weeks "off" - I'm a stay at home Mom, so it's not like I get days off - but after 2 weeks when my husband went back to work and all our help left, I was able to care for my little ones (ages 4 and 9 months at the time), do laundry, cook, clean...the usual routine. About the only thing I wasn't doing at that point was driving - I waited until about 8 weeks after surgery to do that.
It's normal to feel frightened. I get that way when I go to the dentist for a cleaning, so heck - you can imagine how I felt before my surgery! I think you'd have to be crazy to not be a little on edge over surgery - of any kind. Just know that we've all been there and we made it through!
Good luck and hopefully you've gotten lots of good input here. I know I have!
