can someone write down a little getting started for the first few days.
how do I get food/something to drink?
and I didn't have enough space, so I put my things in the box to the right of my house.
did I through my stuff away? can't find it anymore.
Well, first off, the box to the right of your house is the shipping box. Anything you put in there is sold at the end of the day and you get a breakdown of the earnings when you sleep.
You can craft a chest via the crafting menu with 50 wood.
Early on, foraging stuff like horseradish or spring onions (these should grow daily in the southeastern portion of the Cindersap Forest south of your farm) is useful for some energy. At level 1 foraging, which you'll probably obtain just by chopping a couple trees here and there, you unlock the Field Snack crafting recipe which is made from one of each normal tree seed. You can easily obtain these by looking around your farm for acorn-like objects and hitting those with a tool. If you don't receive a seed, it means that particular one had already begun to grow. Field Snacks are worth 45 energy which is pretty fantastic for how easy it can be to get them early on.
You can buy the first backpack upgrade for 2000 gold, which sounds pretty bad but doesn't have to be. I'd highly recommend fishing a lot in the early game as it's a fantastic source of money, especially early on. The fishing minigame takes some getting used to but if you stick with it, it's really not that bad. And fishing becomes easier as you level it, which happens quite quickly if you fish a lot.
My plan at the beginning is usually to spend my starting 500 gold on more parsnip seeds, bringing me to a total of 40 seeds day 1. I plant and water all of these then chop a couple trees, run around meeting people etc. Willy sends a message on day 2 or 3, at which point I just start fishing all day while keeping my crops watered. Between fishing and the parsnips you'll no doubt have the backpack upgrade by day 5.
For the most part, though, your first time through should just be done at your own pace. There's nothing that you can permanently miss out on, so just don't get overwhelmed and let the early days be a learning experience.
