Yes, you must tell your mom! I am the mother of 4 children. My oldest son suffered from depression for a time, and it was dreadful for him and nothing to go through alone. There is nothing to be ashamed of with depression. It is most likely a chemical inbalance which can be adjusted with medication. This is no thing to go through by yourself, honey. You need medical attention and your Mom will help. On a personal level, I also went through a depression of sorts when my 18 yr old died 17 months ago. It definitely is not easy. My best to you...
