my mom wouldnt let me do that cuz she thinks it will harm my laptop for good, now what do i do?
Hopefully you were clear on updating to latest supported Windows 10 release... not Windows 11 (which I'm guessing your computer isn't offering to begin with, but just in case, for the moment .... I'm avoiding the hot mess of Win11 for the time being as I don't have a specific need for it... I suspect a new computer later this year will effectively require Win11... but other discussion)
Then in addition to qhobbes excellent suggestions, the next step may be learning how to 'optimize' an under-powered computer. There are numerous default settings in modern operating systems (Windows, MacOS, etc) that are more 'eye candy' than functionality related, and those features suck up CPU and RAM. And there are processes running which you may not need. BUT.... beware YouTube and similar recommendations from folks who have NO idea what they are talking about (and there are a LOT of those)... you can truly mess up your system if you aren't deliberate, careful, well-researched and have a backout plan [ie, you could end up having to do a fresh OS install, with all that implies, which includes possibly losing some data, if not careful]
And make sure you have Exited (turned off) applications not in use, reboot at least weekly (I reboot daily), etc
All of this is to make sure you computer is using as much of its hardware resources for the OBS Studio processing as possible (with under-powered system) vs other/unnecessary processes
