There is a website called "Sensei's Library" that contains a huge amount of information about the game. It has several pages that are just glossaries, but there is also a separate page for each concept.
At the end of the game, the game has not ended. L11 is still huge: W gets 28 pts of territory in this area if he seals you in, and you can ruin most of it if you get out. You can capture at B13 for an 11 point swing. If you play F18, W will never be able to rescue the stone along the edge, even if he runs all the way to the edge of the board. In the ensuing chaos, you might capture E15 and E17, too. Meanwhile, in the same area you can play H16, which threatens to capture two stones at once. W can only save one. (There is also a slightly more complicated sequence, in which you play J17 and then M17, which might lead to you capturing the top.
This suggests to me that you might benefit from playing on a smaller board (9x9 instead of 19x19) until you're able to keep track of everything that's going on.

Take these comments with a pinch of salt I ain't that good.
You might start at the end and see what happened. After you both passed there were a lot of plays left for black:
e.g B13 by black kills the white group
F18 starts a large invasion
L11 starts another invasion
Looking at the overall game when it had finished - look at how clumped together you are. Many of your groups lived but they are full of stones and made little territory. You tend to "connect" by joining up stones - this isn't the best way to cover ground and "surround" your opponent. You are trying to surround him. At the end he has surrounded all your groups (ok there are weaknesses in his stones but the principle remains).
Move 103 is special. The "empty triangle" black created is a very compact and poor "shape" - it has few liberties. At this stage - don't play that shape.
A big point. You attack from a distance. Rarely if ever attach to a lone stone eg move 157. This just makes a weak stone stronger. R14 or O17 are better attacks that usually result in sharing a corner... If you play chess - just imagine that all your stones are "knights" and attack and defend accordingly... Bit simplistic but there's an element of truth in it..
i just found my 'pass' move was wrong decision, that time my mind is all focusing to make my group alive. i didn't look out for invasion potential, and about making eyes, i thought that the game scoring is chinese not japanese
