You don't "need" friends. Why do we need friends? if we think we need friends then there a self love issue there. You should be comfortable with yourself before wanting to be around anyone else. Yes we can socialize with people as we go out, but it's not a need in life to have someone in your life. That's just society saying "if you don't have friends, or a girlfriend/boyfriends, then you're some sort of weirdo" If you think you need a friend to depend on, you need to work on yourself. It's not right to be looking at other people for happiness or feeling like they will fill a void in your live. You are the only one who can make yourself happy. We are born in this world alone, Scientist, say "people with no social life die younger" lol if that was the case then everyone who was alone all the time would be dying out in their 60s hahah. So yeah we don't need anyone in life to be happy. If loneliness was caused by being alone, then we would all be lonely every time single were alone lol Some people out there like being alone, so how can it cause loneliness? So it's your thoughts causing it if you think you need friends or feel lonely. External circumstances are never responsible for something you feel. Thoughts cause suffering.
