Basically, you should plan on - to start - eating lots of healthy food, lifting weights 3+ times a week with a non-stupid program, trying to get enough sleep, and doing your best to avoid drugs and alcohol for the next 5 years, and then see where you stand. Then just plan on trying to do that for the rest of your life. Being 15 years old and feeling awkward and not-good-looking is what most people go through to some degree. You can help yourself out by starting to lift and get strong way earlier than I did.
P.S. I don’t care about weed - I don’t find it to be harmful for myself, but if it affects your motivation, chill out, and you’re 15 with a developing brain, so chill out regardless.
