And I actually also kinda feel kinda exhausted and tired when I stand up from a screen or from sitting too long

Totally, it's pretty normal to feel a bit tired or dizzy sometimes when you stand up super fast, especially if you've been sitting for a while. Your body kinda needs a second to catch up and get the blood flowing everywhere. It's called orthostatic hypotension, which is a super fancy way to say your blood pressure drops a tiny bit when you change positions.

Being tired in general can make this feeling happen more often, so it's a good idea to think about how much sleep you're getting and if you're drinking enough water. When you're growing up, your body is doing all this amazing work, and that takes a lot of energy. Plus, around your period, your iron levels can sometimes dip a bit, which can also make you feel more tired and dizzy.

If it starts happening a lot, or you feel really dizzy like you might faint, it's always smart to tell a grown-up just to be safe. They can help you figure out if it's just a normal growing-up thing or if you need to check in with a doctor. Staying hydrated and not popping up super quickly from a squat or a really low chair can sometimes help.
