Yes, barre chords can be a pain. I avoided them for years until I figured a few things out
with experience.
Make a slight curve to your index finger and concentrate only on the strings you HAVE to
push down for that chord. Also keep your barre finger as close to the respective fret as
possible.
Also consider your guitar. The setups on some guitars make it hard to play regular chords
not to mention barre chords. Check out your setup by comparing it to others in stores.
If you find it much easier to barre chords on a new Taylor for example, which usually has
very low action and is easy to play, then you might want to consider having someone set up
your saddle more to your liking.
