When I shop for groceries, I always make a list. I buy exactly what's on the list, no more, no less. Relatively normal so far, but wait. Everything I buy corresponds to a specific meal, including exactly how many meals I can make with a given item. I then consume everything in careful order of perishability.
I know what I'll be having for every meal, for the next seven days, when I'll need to go shopping again. My fridge never has old food in it, aside from a few condiments. If I didn't shop this way though, my fridge would never have food in it at all. This is the level of organization I need to deal with going to the grocery store.
Incidentally, this is why I usually decline when offered to tag along with anyone else. Planning around other people can be challenging. Is this a being on the spectrum thing? I'm not inclined to be organized. I do this because I'm so severely disorganized.
My mental health has been very unstable these last few months. Sometimes I've been ok, but then I keep crashing hard. Dangerously hard. I need to hold it together and move, but you'd be naïve to think necessity will force me into doing what I need to do. Stabilizing my mental health is more important than ever at a time like this.
I'm not sure what I need to do or when. I keep trying to make a plan, but the plan depends on where I'm going. How I pack and organize my stuff depends on what I'll be able to use, store, or leave behind, but that depends on where I'll be living and for how long. I've realized that a major source of instability is not knowing that. I keep thinking, it's crazy that I have to manage all the typical stress of moving, without anywhere to move to. This is an awful lot of work just to be homeless.
I've been finding it extra difficult to search for a place, when finding one might be impossible, necessitating a completely different plan. I'll get some help from my family out in Colchester, but they can't seem to decide how much they're willing to help, and unfortunately, I may need a lot. I'm acutely aware of what an imposition that is, but I'm drowning here, thanks to the housing crisis of a political system that only serves the wealthy.
Some rich scumbag buys the place and evicts me like its nothing, so that he can gut everything and renovate it into much more expensive housing. Now I'm screwed, just another victim of gentrification. Other countries just build housing for people. Here, we make it illegal, to keep real estate prices going up.
More to the point though, is that I need to know what I'm doing, so that I can plan around it. When I have time to think about all the ways to make a given circumstance manageable, I calm down and can think about dealing with it. When my options keep changing, it's like having the rug pulled out from under me again and again. I can't depend on any of it. don't know what I'm doing. I don't know how to plan for it.
Without a plan, all the normal stress of moving is compounded, involving terrifying unknowns that I'll be expected to deal with when I'm having a meltdown instead. That's not going to go well.
This is why I initially jumped on the prospect of living in a tent in their yard, instead of thinking about it as a last resort. Despite all the problems with that, I was relieved having something to plan for. I focused on all the ways I could make the most of the situation.
When they changed their minds and decided I couldn't do that, I fell back into the chaos of trying to figure out what I was going to do. I start thinking something else might work out, and then fall apart again when it doesn't. I need to know what I'm doing, or I'm not going to do anything.
Planning has become a critical tool in how I manage my mental health. Without it, I can't function. This is not an issue I need to overcome. It is how I've learned to overcome a much worse issue.
