Can Someone Give Me Some Advice On What To Do

When Bot lane is feeding and I am not winning my lane? This is not a QQ thread or complaining, I am 100% legit asking what do I do here.

To elaborate, what do I do if by 10 minutes my Bot lane has given the enemy bot lane 8-12 kills and I am not exactly winning my lane, maybe we have killed each other or maybe no one has died but I am down 10-15 CS?

This happens pretty often actually and instead of continuously crying about it and not knowing what to do other then surrender when their ADC has more kills than our entire team, I am trying to figure out different things to do.

I would TP to help them but if they are losing a 2v2 pretty badly, there is no guarantee we will get anything from it. They may get some breathing room to farm, but i lose out on 2-3 waves and possibly even my turret going down. If my lane opponent TP's with me, we risk losing the 3v3 in which case they get bot turret. It just seems like there is no chance to TP bot lane unless I have killed my lane opponent. Usually they are feeding the ADC 5+ kills before I even finish my first item, so its even harder for me to want to TP down there since I am so weak.

I try to create pressure Top, but if I am not beating my opponent I am putting myself at incredible risk. Most likely my team won't do any objectives even if I spam ping them. So I can't rely on my team doing anything while I am creating pressure in Top.

I would roam Mid but I fear my lane opponent also roaming mid and us losing a 2v2. Then there is the chance that the enemy Bot lane, who is really fed at this point, also comes mid and it is a 4v2 or 4v3 (assuming our Jungler comes to our aid).

I am not whining here, but it does honestly feel like I need to Solo carry or we will lose. If I am not strong enough to kill a couple of them, we will lose. It is a lot of pressure and I feel like it is making me play worse, on top of the fact that I am not even surprised anymore to see the enemy ADC 6/0 by 8 minutes. I think I have a sort of "we are going to lose anyways so unless a miracle happens I don't care" kind of attitude nowadays and so I just need a bit of advice on how to start solo carrying.

Edit: Just to be clear its not like its effecting me outside of the game, I don't really get tilted anymore. I get irritated but once I close League, its usually done with. I just want to have fun in the game again and its hard to do that when you don't even lose anymore, you just get absolutely and effortlessly dominated... Winning too is soured by this.
