Tired and stressed out

My eyes are seeing things differently today. It's like the "power" is a bit off. I think it's due to lack of sleep lately. The new school term and all-new routine is killing me. I cant complaint, nor can i rant about it. I just have to take my daily grind with a deep breath each day. The walking up and down is also taking a toll on my poor knees. Geeee.... better check out some of these joint supplements here. Wonder if i can find something for my knees or not.
