LIFE SUCKS

Hear me out.

I want everyone who is reading this to know: I live a very comfortable life. I should have nothing to complain about. I, myself, am the sole reason for all the problems I'm currently experiencing in life.
I am a 19 year old currently enrolled in school for court reporting. My mother is having financial problems and, as a result, is always pressuring me about graduating. The profession is very demanding and requires me to practice at least 2 hours a day. I want more than anything to get out of school and start working but the thing is that I've always been extremely lazy. I used to cut school almost everyday when I was younger. My mother would drop me off at the entrance and I would wait for her to drive off so I could take the bus to town and hangout with friends. This is when things started going downhill. I started to smoke weed a lot. At first it was just a couple times a month, but it gradually turned into a daily habit. Two years later, I am still smoking weed daily. My mother knows about my "hobby" but she has no idea that I smoke everyday. She thinks its a bi-weekly thing or something.
Now here's my problem: I CANNOT QUIT FOR THE LIFE OF ME. Reasons for me quitting are obvious. For one thing, it's ruining my health. I can't play basketball for 10 minutes without wheezing. It's not just my physical health either. I have been getting more depressed over the past 10 months. My laziness has also been exacerbated. I used to practice at least 45 minutes a day. Now I don't even have the will to wake up and go to school. I have cut almost everyday this semester. My mother has no idea about any of this. I want to get over this slump and get on with my life like this never happened but it's almost impossible. I think I'm either really unmotivated or really weak-willed. I know my story isn't even an eighth as bad as any of the others in this forum, but I feel like it's going to ruin my life just the same. Anyways, what I really wanted was just some advice. Anything to get me out of my situation. A-N-Y-T-H-I-N-G! And thanks for reading this far.

P.S. This is the first time I've ever posted on a site like this.
