I was going to be a dick and troll you, but decided not to since everyone has felt like this at one point or another, I know I sure have.
Alcohol is a depressant, meaning it will only make your current mental situation worse. Especially when you use it in the manner you do for "boredom"
Cut that out
Stop eating fast food and other bullshit, it isn't bad every now and then but everyday it's bad.
Substitute pop with water, I rarely drink pop and it made me feel awesome. Try to hit a gallon a day, your dick will be Niagra falls for two weeks or even a month because it will just be flowing through you, but once you are hydrated awesome shit happens. Thoughts come quicker, not as sore.
Start stretching
Even if it means walking a mile, or working your way to that, exercise. Dem endorphin's
To be honest you are an asshole most of the time, it is kind of annoying and I can count on one hand the amount of times I've actually had a somewhat serious conversation with you, most the time I'm the butt of some pathetic joke you are trying to crack in my presence or you just do a great job of making my girlfriend feel very uncomfortable which isn't cool at all.
Make a goal of paying off debt, living debt free, losing weight even if it is a small amount, 5 pounds or whatever. 95% of the people I see daily could stand to lose a few pounds I include myself in this. Start with small goals and work your way up so you don't give up as easily and see progress.
I was depressed for 2 years after my dad died, couldn't think right at all and didn't make good choices. I had a lot of fun but looking back I should be in a lot worse shape than I am now. Finally found a car that got me interested in something other than thinking about him for a year then it fucked up. After that I was always hearing bullshit about it and whatever else. Couldn't stand working on it, still can't which is why I am starting something else.
