It seems to me that emotions and feelings come and go... eventually. Everything changes and nothing stays the same. Try not to struggle too much with the meaning of life question. Try letting the thought come and then gently let it go, don't hold onto it. Go for a walk, exercise, watch a fun TV show or movie, call a friend, take a warm shower or bath, get some markers or crayons and draw, ask other people what gives their life meaning. Sharing your struggles has helped me think of what is meaningful to me. Thank you. You are in my thoughts. Hope things get less weighed down by the depression.
