I like Slippin_Lizard's advice. This way you won't let this get you down.

A suggestion I read somewhere was to put a capo on the first fret. This will limit you to barre chords from the 2nd fret up, but it will help you develop the strength and mechanics. Putting the capo on the first fret will lower the action and make it easier.

Also, you could try praticing barre chords on an electric guitar if you have access to one. It is much easier to do barre chords on an electric rather then acoustic guitar.

Be patient...it will come. Everybody goes through this at some point.
