Too many games in progress at your level.
Bring it down to down to about 10.
Looked at a few games. Some are very entertaining.
You won it, but should have lost it.
Missing 20...Bg4+ telle me you are moving far to fast and your tactical
play is grim to say to the least.
Take your time, stop messing about in the opening, develop your bits and
get castled. CHECK ALL CHECKS and if you can, get a book on basic
chess tactics. (The Library,ebay,2nd hand shops...) You will crack 1400
by avoiding silly blunders and simple tactical know how. It's easy.
Also resign if all hope is gone, players spend more time looking at and trying
to save totally lost games than they do the games that are still in the balance.
This is wasted effort that affects the games that are not lost.
