lifereallysucks89,
I have had my periods in life where I have felt depressed (but probably not clinically depressed) and this is normal for most people. I can see that you are feeling down because, as you say, you can't seem to click with others in conversation, and let's face it, communication with others is an important facet of our lives.
You're worried that you don't know what to do with your life, while when I was a student I really didn't know what I was going to do either and it is hard to get motivated until you find something that really interests you.
Don't be so hard on yourself. If you need to talk to someone, then send me a private message or we can talk on this forum, but I believe that if you discuss what is on your mind and we delve into those things that you like in the world, you may be able to find the purpose that you seek and begin to see the path you are to follow.
Keep in touch, we care.
Wendy
