Going to off myself when I get the money to buy a gun

Im an 18 year old male college student, and I’m home for the summer but have no friends and nobody to talk to, just myself and my thoughts… I can’t take it anymore. I almost failed out of college last semester because I slept through half my classes and stopped doing my work. There’s a lot of cool people I’ve met at college but I’ve slowly been distancing myself from them because of what I’m going to do. In 2 weeks I start work for a month and the tuesday after I finish work, I’m buying a gun and taking a bus somewhere way out in the country to do it. A feeling of dejection, desperation pervades every waking moment and I can’t go on….
