I believe you just perfectly summarized how I feel. I need the time to myself sometimes but at the same time I need to be surrounded by people. It’s a really weird situation. I think it’s why so many of my friendships don’t last… as you said the two often alternate. When I’m needing ME time — I push everyone away. Except my husband and kid, but even then sometimes I’m like I just need to go out by myself for a few hours. But when that cycle is over I’m probably the most needy friend ever, wanting to do a bazillion things to hold me over until the next cycle of ME time comes around.
