So I cry a little, cry it out, go to sleep when I'm tired, try to calm down afterwards, and 'tidy things up' in my head.

Sometimes it's helpful for me to go out for a long walk, or do something exhausting. Like running, riding bike, doing excercise.

But most of all... I guess the best antidotum of all is always the warmth of other people... :) It really makes you feel better when you know that there is someone out there who cares for you.

I guess it pretty much depends on the factors which made me feel so. When I'm feeling sad and lonely "just because"... I mean... when some sort of sad&lonely mood catches me all of a sudden, I look for contact, for a little friendly presence, doing something together, and it's usually enough to bring me back to normal again.
But when I feel sad and lonely because something bad has happened... I don't know, for exaple: someone important has hurt or betrayed me in some kind of way - I tend to lock myself up and try to deal with my pain or disappointment.
I always listen to music which helps me abreact then.
I can't tell if it's better for me to "talk it out" to somebody or isolate until the storm is over - 'cause it really depends. Sometimes I feel the need to talk and sometimes... I really need to be all alone. I don't cry much in my life (which doesn't mean I have got no feelings!) but in some situations... it does me good.

sounds great!
