Those friends of yours you see on Instagram weren't born good at it - they just practiced more than you. Look, "talent" for drawing is almost always just practice in disguise. People who draw well have been doing it for a while, period. You don't need anything special genetically to learn; you just need to start and stick with it. Your first drawings are going to be weird, everyone's are, but that's completely normal and it's exactly what you have to go through.
With whatever you've got at home, you're all set to begin. A regular pencil, paper, and an eraser - that's all you need. If you have pens, markers, or even crayons, great. The quality of your materials basically doesn't matter at the start; what matters is that you don't give up thinking you "don't have the gift." Start by drawing what you see: a cup, your hand, plants you have lying around, whatever. Don't try to do anything complicated yet. There are free YouTube channels and sites with tutorials that'll walk you through it step by step if you feel lost.
What's really going to turn things around for you is drawing a little every single day, even if it's just twenty minutes. Don't wait for the perfect moment or the ideal sketchbook. Grab a piece of paper right now and draw something terrible; the next day draw another terrible thing; after two months you'll be shocked at how weird your first drawing looks compared to what you're doing now. That's all you need to know.
