Serious question, what is your diet like? Even if you are fit, poor nutrition can make you feel lazy, sluggish, and unmotivated to do anything.
I'm not going to preach about changing how you eat to better yourself, but there are things you can add to what you eat that are a bit better for your body, make you feel more motivated, and may help pull you out of your rut.
Not going to get too deep into myself, I don't like doing that, but to keep it brief, growing up as a teen, I was a fat loser, depressed, and suffered from extreme social anxiety. I literally pissed myself during a verbal presentation in 9th grade in front of class. I felt like a useless shell of a person that would amount to nothing.
I was afraid of people, was shy, replied with one word while I stared at the ground. I knew I needed to change myself and my life before the remainder of my existence was just miserable and alone.
Without even considering it for a day, two days after high school graduation, I joined the Army. They nearly didn't accept me, and this was right after 9/11 and were desperate for enlistees. I forced myself into a challenging, social scenario in an effort to make a fast drastic change. It worked, not only did I leave out of boot camp being able to look people dead in the eye, standing tall, with a firm handshake and confidence, but I was overall more healthy, my body was fit, and started attracting the opposite sex. I didn't need pills, or therapy, I needed to shock my lifestyle and put myself in a very difficult process that I conquered.
I was changed forever. I'm not saying go so drastic and join the military, but put yourself in an uncomfortable, challenging scenario and push yourself to the limit. Don't just exist and melt away. Start to change today, and don't look back. You may be surprised at what's buried deep within yourself.
I've been eating twice a day for a while. When I was vacated, the only way allowed for me to return is if the stove and kitchen sink were removed. I only have a fridge and microwave now, so I assume you know what types of food I've been eating. I actually was going through a very dark time when all this came at me and wanted to join the military for the wrong reasons. I just wanted to be sent off to a place where I could die. As I said in a previous post, I'll never commit suicide or cause serious harm to myself, but I don't exactly have the will to live either. I respect what you've gone through and glad you were able to pull through.
I was similar in high school. I was a loner. I had people I said hi to in the halls, but they weren't friends. I had way more problems at that age with social anxiety, couldn't look people in the eye, my older brother told me to tell anyone that ask if we're related, that we're not. My high school years weren't fun, I couldn't deal with it so I dropped out in 11th grade. ---
