Matchmaking phenomenon

While my primary purpose for this post is to vent off some anger, I'm wondering if I'm the only one suffering from this.

As of late, I've gotten a job and can no longer play 10-20 games a day because I get off of work at 8:30 and I'm a student. My number of games has since then averaged out to around 2 a day. However, I'm not sure if it's just because I play at a later time or if it's coincidental but I've noticed I very commonly receive the short end of the stick when it comes to teammates (The kind who run out of a kindred ult or play Teemo+Heimer in bot lane). It's really frustrating and to be truthful brings out my toxicity (I've thus begun to /mute all in order not to hurt my account or myself as a person). Is it just my elo? (Silver in flex, bronze in solo) because the enemy always feels more capable mechanics wise and rotation wise. I'll have laners who don't back up when pinged that they're being ganked, mid laners who don't help when I ping for a 1v2 (I try to make sure that a wave isn't crashing into their turret, but then they proceed to yell at me for "feeding" when they were farming in the middle of lane) and bot lanes who just won't play safe when losing. I'm a jungle main and I'm trying to improve my personal play but I'm not sure constantly racking up losses is cutting it for me. It also feels like the better I do, the worse my teammates are.

Is there any way I can improve my personal play to better assist these kinds-of people or do I just have to feed every game so that the carries awaken?
