I think the thing that sucks worst about depression is the effect it has on those you love. I didn't realize I was struggling the last three or four weeks. It was a bit different than usual. I just didn't want to really be around anyone else. Even people I love dearly.
Glad I have such understanding friend and family.
If you ever struggle with depression, I hope you talk to a professional and your close relations about it. When light hits darkness, it makes a huge difference.
