How to Prevent Losing Tower in Bottom Lane?

So I'm a support main who is relatively new to the game (been playing for about 5-6 months) and I've noticed in a couple of my games that I end up losing bottom tower too quickly. One instance where this happens is if the enemy jungler decides to gank bottom lane while I and my ADC try to run back to the safety of our turret. One of two things happens here.

1. I and my ADC fail to outrun the jungler and enemy ADC/support. Either one or both of us die, leaving our turret exposed to the point where they end up depleting at least half of its health before we are able to return to our lane.

2. We are successfully able to outrun the enemy team, but they have the upper hand as they have three in the bottom lane vs two of us. Because of this, they have free access to aggro our turret, depleting its health. We cannot do much to defend besides occasionally poking the enemies in hopes we do not die, and at times the jungler is too late to arrive before the turret becomes destroyed.

I heavily ward the river bushes, along with the bushes that are nearby the turret, and ping my ADC to fall back if they are pushing too close to the turret if we have no vision, but at times they do not listen to my pings. Sometimes they play too aggressively to the point where the enemy team has an advantage of them and I cannot keep up with them. Should I try to play more aggressively with my ADC?

I also understand that recall times and minion waves also have an influence on a turret's lifespan. Sometimes if I feel as if my ADC is recalling too early due to being OOM or HP, I try to stay in lane and at least freeze the wave somewhat so that our team's minions can push. Should I recall at the same time as my ADC? Is there a clear method of "freezing" the minion wave?

I understand that with the current meta, turrets are in a very weak state, but what can I as the support do to prevent the loss of my turret? Any help would be greatly appreciated.
