15 year old girl, is weed stunting my development?

At 13/14 i spontaneously broke out into a fit of anxiety in the middle of the night, that would be the start of a never ending cycle dealing with hyperactive stress. I would wake up at 4:00am every morning to the sensation of being smothered and intensely painful cramps in my stomach, and the only choice i had in the  limitedly nurturing home of 3 brothers and an excessively busy single dad, was to suck it up and cry into a pillow until the adrenaline wore off and it was time to go to school hours later. Eventually it became too much of a handful for anyone to handle so they pulled me out of school and sent me to the learning center twice a week until i finish my credits. Still i was forced to deal with the anguish of anxiety which caused extreme physical symptoms, which included nausea when eating and awakening, which developed into became so painful i just stopped trying. At the time these were my marks of puberty: irregular periods seperated by multiple months at a time (over all i only had about 2 that year) budding but zero breast growth, some pubes and thats it. Anyways im 14 and pick up my first blunt. All of a sudden i have a remedy to help me eat, fight nausea, step outside even. I felt really good, and there was no reason to stop so i never did. Since then i havent missed a day of medicating myself atleast once in the morning and atleast once at night. Sure i forget things, but im no longer a catatonic vegetable. One year later, Im 15 and today i had my first period since, FOREVER ago, and my boobs are about 32/34 A, but generally smaller than every other person ive ever met. Im gonna be 16 in the coming january which is months away. Im curious, could weed be stunting my breast development? If I stop smoking will my periods come regular? And not that i dont like how i look now, but if i stop smoking will my breasts grow too? What if weed is the only thing holding them back?
