Childhood depression?

Yesterday I woke up feeling very groggy. I went to pets at home to get some supplies I was running out of for the guinea pigs, I came home and played with them while Paul cleaned the cage out and then I felt really tired so I had a nap. I woke from my nap feeling much worse. Sore throat, headache and blocked nose. And I’m so cold. This isn’t good. 

I’m working extra this morning for double time but I really didn’t sleep well & I have a sore throat, ear ache and still feel very cold 🙁 GREAT. 

I haven’t really been doing much thinking over the weekend. Although because I have been reading my old entries I got to thinking about why I suffer with depression and when I had possibly had it for the first time and it suddenly hit me than when I was younger in high school I was bullied and around the same time I was also off school a lot with chronic fatigue or ME the doctors thought it might have been. But looking back I can see I was depressed. How the hell did doctors not pick up on my feelings? Was it not a big deal in kids 15 years ago like it is now?
