Hi! I have lived with depression for many years. Some times are better than others. I have learned how to make the most of the little things which, if i dwell on them deliberately can help me remember that each day has some good parts. That with medication has meant that for many of these years I have had a good quality of life in many ways despite my symptoms. There is always hope and a good chance that you could do even better than me.
I hope this is of SOME help, this response is from experience and from the heart, not just the platitude of someone who hasn't walked the walk.
