Hi bluebearTIN
Welcome to PC! I'm glad you found us here.
I'm sorry you are feeling so down and having problems with headaches. I think it would be a good idea for you to see your doctor and explain to him/her what you are experiencing. You may have some physical problems that could be causing your pain and missed periods. It would be good to get checked out so you can rule out any physcial illness.
Talk to your doc about your depression too. The doc may refer you to a therapist. I find it very helpful to go to therapy when I have some problems I can't seem to solve or work through on my own. They can help you make sense of what you are feeling and work towards healing.
I wish you well dear and hope you will find the support you are looking for.
