I admire being silly and light-hearted, though if you want to climb you may discover that it requires you to behave a bit out of character.
After briefly looking at your op.gg you have several champions with good KDAs and kill participation but you have very, very few games total. This needs to change. If you want to climb, you should be playing (almost) exclusively ranked games.
As for your role, you seem to perform well on hard engaging supports such as Alistar and Blitzcrank, but you have an insanely small sample size. The only way to climb ranked is to play ranked games.
As for some of the things I've noticed about your games, in general, when playing support you should never be split pushing and very rarely be holding towers by yourself. Think of the game in slightly different terms; all of the CS on the map is a source of income. League is ultimately a game of resource management. Towers, objectives, minions, these things are all resources you have at your team's disposal. Even your champions are resources, respective to their roles. This means that a hard engage support is much less valuable after engaging, while an ADC's or mid lane mage's value increases dramatically the longer a fight drags on.
Imagine a chart with several waves, like an ocean. That would be a rough estimate of an engaging support's value during a fight. Before their skills are on cooldown, their potential value is extremely high as a resource. Once they've engaged (or missed their skills), they have essentially used up all of their immediate value and are now relatively weak resources. The closer their cooldowns are to coming up again, the more value they accrue in a team fight. To contrast this, when there is no team fight occurring, the mage has moderate value stemming from their ability to CC enemy champions or push minion waves. ADCs value is increased or decreased depending on whether or not they are auto attacking. Whether it be structures or enemies, ADCs value is the absolute highest when attacking these things. However, all values are reduced to zero when dead or not attacking.
So I've said all this to say that when you're playing league, remember the role you have on your team and in the game. You should be trying to maximize your value and contribution to the game in order to win the game. This is very likely a different approach to viewing league of legends than most people have at your elo, but should give you some tools and ideas to climb.
The most important part is simply to play more ranked games.
