Is my immune system at rock bottom after staying up all night because of mosquitoes?

Oh, seriously, last night, a mosquito invaded my room and my left arm and calf were all red and swollen. Even at this very moment, I can't type properly because I'm scratching so hard. It's so itchy I want to scream! Actually, I thought that my sensitive skin and severe itchiness were because my daily life habits were so messed up that my immune system was low. I used to eat late-night snacks and watch YouTube until dawn and then go to bed late. You can definitely feel that my body isn't what it used to be, right? So I thought it couldn't be helped and put it in the corner of the cupboard. Health functional foods I took them all out again. Before, I would just eat them once or twice when I received them as gifts, but now I'm trying to eat them regularly to survive. I've finally realized that small habits like taking vitamins or probiotics at regular intervals add up to shape my body. It's amazing how after taking the supplements for a few days, I wake up feeling lighter. Of course, I need to apply medicine for these nasty mosquito bites! Don't suffer like I did and take care of your health in advance. I have to go apply some refreshing water paste now!
