I think it's cause I'm so transparent. I don't mind sharing anything...but I don't want to reinforce ideas like "I'm unhealthy" or "I am poor" or "I have some kind of trouble". Usually I'm really ok and just telling someone "That's why I haven't called you". I wish I could do that without inviting people to focus on those things.
I just use instagram to edit photos. It's the most intuitive I've found that I don't have to pay for.
