I relate to what you say, this advice is good as far as it goes. I am very good at valuing and enjoying the little things which can make me feel more positive. However, at times these things can't reach me. At these times I have to accept that emotions are there and neither good or bad (however painful) and I have the right to feel them. Depression is hard work! Sometimes it's ok to just BE and plod on accepting ourselves for who we are. I like the image of me as a person who experiences different emotions which I can stand back from and watch for a while, allowing them to flow through me. They don't define who or what I am. It's not easy and does not take them away but is more restful than fighting them all the time. I'm rambling and this is not meant to be more trite advice I just think there's a place to give ourselves a break for a while and be kind and compassionate to ourselves. You are strong to get this far, so you can go on.
