I seem to only feel /lonely/, in missing specific people. If I begin to dwell on my friend Akila, and the fact I haven't talked to her in quite some time now, I start to feel lonely again, because I miss her.
Sometimes I feel alone, but this is usually only when I've become very upset or sad because of something that just happened, or when I tried to reach someone I miss, by phone or internet or otherwise, and couldn't get in touch with them (for similar reasons as to why the other makes me feel alone).
It is when the two are happening at the same time, that I begin to run into problems. But it is because of those moments, actually, that most of my friends have been made. When I am feeling both lonely and alone, I usually end up seeking out the company of someone other than the specific person I've missed. If it's way late at night, or some other circumstance is in effect, to keep me from talking to one of my friends, I tend to reach out to people I don't know, or people I don't usually associate with so closely. That's how I met my friend Akila in the first place.
Still, it makes life feel too transitory, to accept things as being like that, so, for now... I check on Hubpages and peek around, I do a quick update to my Facebook apps, and then sleep. Perhaps tomorrow, I'll call Akila, and see why it is she hasn't been talking to me lately...
Good luck to you, and I hope you feel better. <3 Remember your own wonderful mind, that other people love you for, can be adored and enjoyed just as much by yourself, as for them. And stay strong.
