In case you're too afraid to ask, just know that nobody is ever useless. Trust me when I say something great will always happen, you just have to be patient and wait for your time to come. And by waiting, I don't mean sitting and doing nothing. Get up, WORK for what you want to improve, find people/family or friends you trust and express how you're feeling to them. Do as much as you can to change your outlook in life, count your positives and don't always focus on the negative and leave the rest to Allah swt.
