What is the best for me?

I had my hair cut too short. I asked for a sexy angled bob and she mostly shaved all of my hair in the back with the clipper. I thought she was only going to shave my nape
(which I asked for) but when I realized she had clipped the rest of the hair too, it was late.
As a result I am walking around with this "Man like Haircut" and I feel very unattractive. I asked for the money back but my hair was gone anyway.
I want to try hair extentions. I only want it towards the the face and over my ears, past down a little to about my mouth in lengh, angleling up towards the back and leaving the back the way it is.What is the best kind of Hair extention for this case? I just want a little lenght added. I I plan to leave it for about 3/4months and hopefully my hair would have grown enough to where I don't need them anymore.
How bad is the damage caused by the extention, I dont' want to have it all cut off again... Help me please I feel like I lost my femininity along with my hair and it is taking too long to grow!.
