Hi Kenny_B3ar,
I'm no expert, just a MacBook Pro user like you.
If you are low on memory, you might want to empty the trash ... sometimes that helps, if there's a lot of files in there.
You can Click on the little Apple icon at the right of the top menu bar, and choose About this Mac ... then choose "Storage" to see how much space you have left. You may need to trim down how much you have stored, by backing some of your files up to other storage (eg. an external hard drive) or deleting some of your old files,
You may be able use activity monitor to check what is happening with memory:
You can read about it here ... (and clicking on table of contents at the top of the page that opens. reveals more info.)

Hope you find something useful in these suggestions.
Cheers
