You are valuable! It isn't a helpful path to try to find proof from others that you are valuable. People are so caught up in their own lives, that they 'forget' about you at times. It doesn't mean they don't value you. I have been down that path and am super aware when I am left out. I am quiet and it happens a bunch. I want people to let me know they care....I want them to prove to myself that I am worthy. I want people to show me a little support. Unfortunately, people don't always let you know how they feel about you or even recognize when you are struggling. They assume everything is fine. I told a friend recently that I was feeling down, and she was surprised and had no idea and was very supportive. It might help to open up to a friend.
