Sometimes i am so dumb, it's scary

So whatever i put down trash container to the street i never fasten it. I didn't even know it has breaks, so today my mother put container in the street and after trash was taken, i wanted to take IT back to the yard through gate. Of course breaks make it harder to push and our gate has elevation. The trash container is big, because we share IT with another household, so it really looked comical. The middle aged man had to come to me, while i told him ,,thanks, but i could do this myself", because i was already ashamed. He despise that put breaks down and helped me go through this elevation. Of course i thanked him, but i am so full of shame. Whatever i try to do better, I always make something incredibly stupid. I don't know what is wrong with me. Maybe if i didn't spend so much time mindlessly scrolling and making sponge of my brain, I wouldn't be like that. I am lacking basic knowledge and my brain shuts down completly outside of home. At least i look much younger than my actual age, but still, even for a child IT would be so dumb. (Not a native speaker)
