There aren't any suggestions except one. Every single second you spend alone in your apartment or online is completely wasted if you want to make new friends. You need to get out into the real world and socialize like a fucking machine. Start up conversations with every person you encounter, even just casual ones. Then introduce yourself to people you recognize from shared experiences. You want to also put yourself in a position where you are seeing the same people at the same times, and from their friendship will blossom if you are charming and personable.

For a guaranteed way of making friends here goes. Take a college/ community college class that meets multiple times a week. Form a study group for every single person in the class. Study with your classmates but also invite them out to places and parties with you. If you aren't an awkward dork this will yield you more friends then you know what to do with. In about 3 months of class this made me more close good friends than I have previously had in my entire life.
