AN ASAP NEED FOR HELP FROM A NOOB T^T

Hello, I have been heavily struggling with ranked games in a few recent days.

I have lost straight 100% games starting from my promotion to Silver 2 into silver 5 30pts. (As you can see, people call me a piece of noob shit :D or something worse than that, I can't remember exactly?)

As what I remembered according to my games,

-None of my teammates pushed but we got utmost 1 tower, not the end of the world (sarcastic voice) ^_^

-I think I have terrible skills on my own about map awareness at certain points (maybe) as a support. I can't do ay damage to the other team because I have 0 damage. I only have peeling abilities.

-As an adc, I tried to stay back and attack what is in my range (most of the time). _However, I started to split push as the enemy team are all present on the map in teamfights so I could take some objectives for my team. I didn't know what I should do: group with my team and fight or split push since the enemy team split pushes a lot (they just push with ease and I can't stop them)

I HAVE THIS ONE QUESTION ABOUT THE SMALL PARAGRAPH WRITTEN ABOVE Am I making the right decision? Or am I just a piece of noob shit? Or worse?

I would really love to have an advice about this whole decision making thing. I really want to go to Gold or at least right now go to Silver 2. I'm very scared of going to bronze which devastates me a lot. I don't know why am I losing a huge streak like this. I usually just go in and have a game that at least wins.

I really appreciate the comments and advices from the sunbaes and senpais here v.v

Bianca.
