Well you can try the internet help others make new friends more you stick on internet less you will get depressed from humans.
I think u will less rely on human then anyway but this isnot solution.Maybe doctor can help.

You need to find something that you enjoy doing by yourself. I think what the problem is, is that you're relying on other people for your own happiness. I had the same problem for a while. You just need to look inside yourself and find reasons to be happy. To get over it when I was going through it, I simply sat down and thought about the reasons behind me not being happy and couldn't really find a good reason, so I just became free spirited and took things as they came. I lived each moment as it came and didn't worry about what the future would bring, or the next second would bring or any of that. I just lived and was happy because I could be. You'll notice that people will be drawn to you when you're happier too.

You might be depressed. Perhaps you feel lonely when you aren't with these people. That's not normal to feel that way. I think you should seek help.

I feel the same way as the author...i have been this way for most of my life. I can't remeber a time where i have been more than a few days of just being happy...its like my norm is to be mildly depressed or something. I eventually started to date and discovered that certian people that i have dated i have become attached to them in a way where i'm not depressed when i am around them. I feel happy and its like being on a vacation at times.Their presences is very soothing to me and i am at ease. I dont like this kind of living. i would rather much make myself happy but the only thing that seems to work is to either be around them or if i am in love with the person, to think/fantasize about them to escape from the depression. It has became so bad that i cant focus in school. I was an academic honor student and entered college and now i am a mediocre student with 2.5 GPA. it's important i overcome this soon. I grow tired of this way of living. Its very exhausting and laced with heavy emotions. I thought maybe there is a chemical imbalance in my brain but i can't afford to go to a doctor..perhaps there are some natural ways/supplements that can help...at this point anything would be good.
