Hi there,
Welcome to the HealingWell Depression forum. Honestly, we can't diagnose you, but we can share experiences with you and let you know that we do understand how you feel. The best thing that you could do for yourself is see a counselor of some sorts and get a diagnosis that way. They would know for sure.
There are many symptoms of depression. Loss of interest, constantly wanting to sleep, extreme fatigue, irritability, crying, pain. And more. But there are different degrees of depression. Some have it much worse than others. But if you catch it early, it is easier to get a grip on it.
So do talk to somebody. Let them know all of what you have been going through. Let us know how it goes.
Hugs, Karen
PS HAPPY BIRTHDAY!!!
