I think i have some kind of anxiety disorder what do you think?

i've been really stressed out about life to the point that i find my existence almost useless, i want to put in the effort to get things done but it seems like my mind just goes elsewhere, like right now im sitting on the computer not doing anything except surfing the web when i could be doing something better with my time, like finding a job, maybe reading the drivers handbook to get my liscense, or working out doing something positive. Instead i smoke pot, do other drugs occasionally, i also take martial arts, im really big into that, and it has helped me in certain areas of my life, if i didnt have martial arts i dont know where i would be, jail or 6 ft under. There will be times where i would panic and think what the **** and im doing with my life, sometimes will think suicidal, i want to progress in life but i dont know how, feel like i have a mental barrier that is preventing me... just like how ocd people go about their life in a certain way, i feel like im stuck doing the same thing over and over.. i think my dad plays a big part too because he enables me to live this way, he doesnt want me too but he never punished me for anything, just didnt distill certain things in me that is essential in life, i feel. My mom is bipolar too, i think i might have inherited some of her traits, but i dont know. what do you guys think? am i just a lazy ************ or do i really have some sort of mental disorder.
