Ok so.. I have always been interested in natural sciences so I'll probably keep on browsing the forum.. but I'm off age when I needed to choose what to study (21) and I enrolled in physics. I can still change that.. Last year I studied Chemistry but Physics was one of the few classes I passed (easily), so I have *some* idea of what university Phys is like.. Right now I'm 'on long vacation' with plenty free time. I used to have many mental problems which kept me from living a normal, balanced life. I resolved them, at least in theory, but I still struggle with heavy drug abuse (I'm strung out). At this point, anyone reading this, if there is someone on this forum who is also a user AND successful in life/studies, I'd be grateful if you referred him to this post/my inbox. I know phys is very logic heavy and requires hard work and memory and I'm unsure if I posess these qualities (anymore). I'm not even sure I'm really as interested in it, but this could be merely my non-ambitious substance abuse ridden environment I live in speaking. I have nothing more to say for now, I am opened to questions/advice.
