Hi MissEducation, welcome to PC!!
Maybe it's not as much you've been in denial about the way you've been feeling, as depression can sometimes gradually creep up on you, and at times you can almost forget what things were really like before the depression when you're in the middle of it.
But it's really good that you've recognised how you're feeling, that you need help, and that you're reaching out for it.
And you know, you're right it would be good if you got it officially checked out including having some general medical tests in case there's any underlying reasons for the way you've been feeling. So maybe you could start with your doctor with that??
But glad you've joined us, you'll find a lot of people on here who can relate to how you're feeling and who can offer you some understanding and support.
Again..........welcome to PC!!!
