Just checking in with you lovely lot
for all of us.
Love the camp site updates 
It strikes me that there's a lot of intelligent, self aware, reflective people here.
I wonder if there's some correlation between people who think more deeply/are more aware and loneliness.... I might be totally wrong here- just an observation from this thread....
That sculpture is beautiful, as is your description of it shots.
I love that Brene Brown video! I'd be interested to hear about/read the book.
I agree that self esteem is a key factor in what we're going through. I think it's cyclical. We draw away from social contact or find it awkward because of self esteem, become more lonely/isolated because of this and then loneliness changes our perception of ourselves and others, thus compounding the issue....
I agree that our building blocks to change this need to be about self respect/ learning to like and practice compassion towards ourselves. I would very much like to feel loved/lovable to others. I know I've got to start with myself.
I know it's a bit woo but I the whole 'law of attraction' theory makes sense to me. (I've never read 'The Secret' though! ) e.g I took a group of adults experiencing depression out as a part of my job. We generated a real sense of 'fun', laughing, being silly/joking, being warm and smiley. I noticed the reactions of others (e.g. Shop assistants, waiter, bus drivers)
'matched' ours- i.e. Smiles, jokes, being friendly and helpful. I do think like attracts like in this way. I know when I'm a bit 'off' people are more likely to be off with me. I know when I'm putting on a smiley face but don't really feel it then I get less positive responses from others than when I genuinely feel good. So that's my long winded way of agreeing that it's so important to work primarily on developing a sense of self worth, knowing we're good company because we like who we are! It can be a battle for me when I feel ground down/rejected/just tired of it all, but my goal is still to make improvements to my sense of self worth, generating a better 'vibe', then hopefully attracting the same for others. I don't know if that makes any sense at all!! But appreciate being able to express it here 
I also agree with PP about being the one who helps others with their problems and ending up feeling alone. That's another thing I need to work on!
