How do you even actually get set up? Why do I feel I can't escape zombies?

I get the whole point of dying over and over but I CANNOT get any type of start at all. I'm not bad at these games by any means but I literally can't avoid zombies. I break into a house to try and break their line of sight and come out the other side of the house to even more zombies. It gets so bad that I end up spending basically 30 minutes running around just to die because once again I CANNOT escape the zombies to find a safe spot. I've tried everything from jumping over tall fences to yelling at the zombies hopelessly tying to group them like I'm playing cod running a train and yet it feels that they endlessly respawn.

I start day one everything is tame. Day two I'm feeling kitted out ready to try and establish anything. Day three I'm running around for hours starting to actually dislike the game entirely because it's just become a running game instead of an actual zombie game.

I've watched all types of videos but it doesn't change the fact that every couple feet its like there's groups of 6-7 zombies. I like the game and I really don't wanna lose interest but that's how I'm feeling.
