bushes are totally useless to search until you got at last 2 survival skill; it take too long to xp on them, and give almost nothing . On top of it, depend of your starting season (spring is defaut, no ?) you don’t have the same output.
Pick a new dude, choose the basic shelter survivor; don’t pick skill, but instead pick quick, and upgrade your str. You may want to pick more carry strength and volume trough trait by picking bad trait like addictive personality, animal discord, clumsy, lightweight, poor hearing, strong scent, truth teller, ugly. If you have 14str, go place them into either dex or int.
That should give you some hp, and decent damage at close quarter on top of allowing to you use some bow/crossbow with more efficiency.
Create; shelter, go down, pick whatever clothes you can that does NOT ampere you. Do NOT pick more than 10 (or 15 if the thing is really good), unless you need it for the cold.
Pick a weapon; fastest weapon earn more from str than slow one, but zombie have armor that may negate bashing damage if you don’t have enough, so best early weapon at this point is something fast (<100) with bashing damage.
If you have something to light a fire, you are good to go, unless it’s raining. if it’s raining, better try to grind some skill (bash stuff around to train you fabrication, make a needle, smash windows to get string, disassemble it, train tailoring - DO NOT cut down stuff unless needed to grind because low skill waste material. Windows have lot of rags; then make yourself enough to protect you from cold)
Then go wander around, piking rock on the way, up to any building you want to loot (house is better because it lack the possibility to spawn something nasty early). if you can do a run up to a windows , smash it twice, and use it to slow down any Z that is fallowing you to attack it while it go trough the windows.
Then loot the house; If you can do in one run, just stash stuff you want to pick near the broken windows for you next run. Eat stuff directly here, drink can;
You can at this point use a can empty to boil water. If there is some water near a windows you can light a fire outside, just enough to get you starting crafting clean water.
If there is a basement, don’t go in. May get you killed. (or try and hope getting some awesome weapon/gun, sometime)
try to get something to boil water (can, or best, pot), go back home when full, trow the can/pot near the computer along with a pointy stick if it’s not a pot.
You can now make your own food; may be annoying until you get decent container though.
if you get anything in range noticing you, go back a bit (5 square or more) and wait for him to come. trow him your stuff when it’s close, you may hurt him a bit with some luck. trowing is really easy to grind alone, just trow something at your feet (ya can do this before even going you, but make sure you have some focus >30); then a sling + pebble is easy to make and a reliable weapon against basic zombie (= they don’t have special armor). Even if you kill it it may avoid you getting one hit or two, so less pain, so more speed for you, etc. All good.
Sadly I can’t see what you are exactly doing, so I can’t pinpoint how you would have so much difficulty early. Worst case it’s not even needed to attack any zombie early now, you can go trough the survival forest way, but it take a lot of time (like, you may not cook and eat “raw fresh” meat because you can’t make a lot of fire). This way to go require at last protection from cold as a starter because you spend too much time outside, and cold will drop your speed and focus, making any move, basically useless. If you have a good starter, you can try this.
