Premature aging? Facial Expression Deformity?Anxiety?Effects from smoking weed?Fluctuating weight? I'm 22!

I squint and play with my bottoms lips. I also have been yo to dieting since 14yrs old. I ran and dance to stay fit and my cheeks tend to bounce. My dad and mom are noticing it and they say that I always look tired. I didn't have these lines before or just not so prominent. I have been smoking weed since 21 and have had massive anxiety and physical changes since 20(joint discomfort,hair texture,shaky hands). I've seen kids with cheeks have these lines as well so what's causing this&how can I fix
