Have you suddenly become a petty, hateful little gremlin who thinks people should face the firing squad for (checks notes) leaving teabags on the counter, breathing loudly, or daring to exist in the same space as you? Perhaps mundane and reasonable requests like ‘hey, we agreed to hang out now, let’s hang out’ make you want to scream and move to a yurt in the woods.

You. Are. Overstimulated.

People talk a lot about being overstimulated, and the physical/mental effects of it. What I haven’t seen is people talking about what it does emotionally, and it took me an embarassingly long time to link up those nitpicky, resentful emotions with the state of overstimulation/meltdown/shutdown.

These feelings do not mean that you’re a bad person! They probably aren’t how you actually feel about the people around you. They probably do mean that your nervous system is at its absolute limit and any request/demand/stimulus is Too Much and taking you into fight or flight territory.

Go lie down in a dark room for an hour, or find somewhere safe and familiar to stim for a bit. If it’s happening a lot, schedule yourself regular low-stimulation shutdown time

Replacing a HDD with an SSD

Adding RAM

Graphics cards if you're nasty

Uninstalling resource hogs like Norton or McAfee (if you're using Windows then the built-in Windows Security is perfectly fine; if you're using a mac consider bitdefender as a free antivirus or eset as a less resource intensive paid option)

Customizing what runs on startup for your computer

Things that are likely to make internet browsing specifically meaningfully faster:

Installing firefox and setting it up with ublock origin

adding the Auto Tab Discard extension to firefox to sleep unused tabs so that they aren't constantly reloading

Closing some fucking tabs bud I'm sorry I know it hurts I'm guilty of this too

Things that will make your computer faster if you are actually having a problem:

Running malwarebytes and shutting down any malicious programs it finds.

Correcting disk utilization errors

Things that will make your computer superficially faster and may slightly improve your user experience temporarily:

Clearing cache and cookies on your browser

Restarting the computer

Changing your screen resolution

Uninstalling unused browser extensions

Things that do not actually make your computer faster:

Deleting files

Registry cleaners

Defragging your drive

Passively wishing that your computer was faster instead of actually just adding more fucking RAM.
