Does watching porn make you depress unoticeably?

I'm in my teen years and slept with like 9 girls and all but after my first love I started watching porn like once every night before bed and ****. lol sounds like im a creep but that's not the point. I realize ive been feeling extremely unhappy the past 2 years. Like when I was in high school everyday was the same shade of grey. All I can think about like "everyone acts the same, look at these Dum *** wearing the same jansport book bags. ******* followers." and ill just think to myself negatively all the time. I just sit there and say whats the point of doing this or that. I mean I'm responsible but when someone wants to chill I'm like "ehhh Whats the point" and Im always so gloomy and don't get excited about stuff like I used to. and I'll have those moment when I'm alone "what now in life?" you feel me? I think The best thing to do is stop watching porn (stopped a day ago) and focus on life instead of feeling like a cant breathe. I dated so much girls but ever since my ex..I don't feel strong about any of them...its like I'm trap in this slump thing but can't get out....so I'm trying to delete any negative energy once so ever. Is this the way to go so far?
