A photo is a photo, after its taken those people go back to their lives, being real people with real problems. Anyone can put on a happy face and look like they have it all and have everything together. Maybe they genuinely are happy. But I assure you their life isn't perfect, no ones is :-)
I wish I had a close family too, im always craving that 'belonging' to something I never had and feel ill never get. I need to work on that, feel like ive been working on it forever and never get anywhere lol...(it's not about you liz!)
Anyway sometimes it's good just to write it all down and get it out. Hope you get to smile today :-)
