Is it right for a doctor to do this? I'm a little upset (ok, a lot upset)?

So I've been seeing my current doctor for about 3 years now. She's awesome, I love her. She's friendly, patient, caring, gentle, understanding, thorough, willing to listen to all questions and concerns and will answer them in a way that's easy to understand...everything you could ask for in a Family Doctor.

However...I called about 10 months ago (end of February) to make an appointment and the receptionist told me that my doctor had gone home to India for a vacation and would be back in a month. I was a tad annoyed because I was sick and really needed to see a doctor, but it wasn't too big of a deal because I ended up going to a walk-in clinic and seeing a doctor there. Plus, everyone needs a vacation every now and again, especially if you are from a different country and don't get to go back very often. No problem.

She was not back "in a month" and when I called to ask when she'd return, the receptionist said "we're pretty sure she'll be back in May". I didn't really know what to say to that, considering they weren't positive on her return date, plus the fact that that was 3 months away! Anyway, to make a long story short, it is now December, she's still not back from India, and the office has no idea when she'll be back. In fact, when I called last week and asked if she'd EVER be back, the girl said "well I certainly hope so" and couldn't tell me anything beyond that. What?????

Is it just me, or does that seem SUPER unprofessional? I understand she needs time to go back to her country and everything and I am not sure whether she just went for a vacation of some sort of "family emergency" or something, but regardless, she has patients waiting for her here and wondering when/if ever she'll return. And by the sounds of it she hasn't even let her office staff know what's going on. She hasn't even gotten any doctors to fill in for her!! (There is another doctor in the same office who is taking patients, but there have been many many negative reviews for him so not many people are willing to see him instead) I know MANY people that go to her, and a lot of them have gotten fed up and found new doctors. I'm thinking it's about time for me to do the same. It just sucks cause I've never seen a doctor with such professional and caring bedside manner, and I honestly loved her for that. Finding a doctor who is taking new patients is hard enough as it is in this city, let alone a doctor like her.

What do you think? I am right for being upset about this, cause I kinda feel bad cause what if something bad happened to her family or something back home? She has every right to go back,
