I feel a similar sense of aloneness.
I think part of it is the effect of medications, some of them really do make us withdraw a bit...if you aren't taking any anti-depressants, ask about
it -- we have physical reactions to these meds, and sometimes need the physical help of an anti-depressant to get back to a place of normality.
The other has to do with the pain & fatigue. I simply don't have the energy to dance around and be bouncy. Do you take anything for the pain or is it constant?
Another thing is living with a physical illness makes us more aware of life's down side, and possibly makes us a little more serious than others -- something that will really differentiate you from your friends at your age.
I think with pain and fatigue management (you may not be getting deep restorative sleep, maybe a sleep study and some sleep medication), added with some anti-depressant meds and possibly some therapy, will get you back to a place where you can feel more connected.
It won't be instant, you'll still have to work to reestablish some friendships, but just something to consider and try.
Best wishes --- it sucks to feel alone all the time, I know!
