Self-coach technique training

Well, I just wonder: how do you do it? I've hit like a gigantic wall of recession for my breaststroke: and I don't even have a bearable time! My time's horrible! I can't understand why I've stopped improving. Unless it was my stroke mechanics?... Hmm... I noticed today that I can't seem to glide very far during my breaststroke, which I think implies something's wrong in that phase of my stroke. Probably too much drag during recovery or some other thing, or not grabbing water with feet. So I'm gonna devote 2 months to technqiues training. But the thing is: how do you do technique training without a coach. I know a lot of people have done it, but then, how do you know good technique from bad technique? Simply by feeling your way through it? I don't really think so. A wide kick feels wonderful - the soaring feeling, but it's bad technique. So how do you train good technique? Thanks a lot. PS: Incidentally, is there a way to STOP ONESELF FROM AUTOMATICALLY COUNTING STROKES?? :( I can't stop, and everytime I start doing it I end up focusing on trying to get a number of strokes instead of ON my strokes.
