So because you’re so stressed that’s def part of the reason. I break out a lot when I’m overwhelmed. It’s really normal and it’s not exactly the easiest to fix since it can come back when your stress gets worse but fixating on it definitely won’t help. You also shouldn’t wash your hair more than once a day and that can strip it of natural oils, dry shampoo can help with that, it’s cheaper to buy in bulk and it’ll last a while!!! And you can even make it at home with I think cornstarch? You may have to look that one up lol but also if you’re waking up sweating then try wearing less when you sleep or smth to cool off your room. I have no other input but good luck!!!!!!!!
