You don't need friends to live. I have not had a single friend since high school. And looking back on it that is a very good thing since those "friends" were nothing but opportunistic users. One of their favorite things to do was make fun of my speech problem. Which completely decimated my self esteem and gave me permanent emotional scars. Since high school I went to two concerts alone and had a great time. I also partook in several hobbies which gave me great pleasure.
