Another New Player

Just wondering, I'm still relatively new, with about 40 to 50 matches under my belt, does matchmaking get better? I'm facing teams that always know exactly what they're doing, how close enough I am to attack me, their movements are so fluid, my team attacking me, telling me minecraft is more my game, the ganks of the enemy team being always on point, the enemy knowing when they have enough to kill me in under 3 levels, etc. The first 20 games were ok, I wasn't the best, but I was facing similarly skilled players, my team wasn't expecting me to be the best, and some games I would get s ranked on my champ, some a's, but overall it was fun and fair, win or lose. Now I don't expect to win since I get killed in the first 2 minutes because the enemy is just so comfortable approaching me past minion waves to literally melt my health, proceeding to go on a 12 and 0 streak on the rest of my team. I don't need tips, I'm getting enough from watching vids and reading posts and all that on the daily, I just need to know if this is how it's going to be so I can save my time and find a more appropriate game where I can apply what I'm learning instead of just being demolished every game. Thanks.
