Hair problems

Okay ladies. So I got my hair done a few weeks back and I over estimated how short I really wanted it cut.. I got it cut to my collarbone. I have always had long hair but I just had a baby so I was thinking I should cut a little off. It was at the mid section of my back Before I cut it. Now I HATE it. Absolutely without a doubt 100% HATE my hair. How can I get it to grow faster?? (I know, dumb question) but I need it to grow out at least a little bit. Because this just sucks and looks horrible.
