Your feelings make sense to me since I suffer from both anxiety and depression. Once during a period depression, I lost my only friend. This made my depression worse but put my anxiety through the roof. It also triggered panic attacks. Later I found another friend and my anxiety decreased. I also then had no more panic attacks. At the same time, my depression was still there.

Maybe it is like having a really bad headache and a really bad stomach ache. The headache goes away but one still has the stomach ache and so still feels bad. Maybe this is not a good analogy.

I am glad your hypervigilance and anxiety have deceased and sorry that you are still burdened with depression. I hope that you will be free of that too since it is a very heavy burden to bear. Wish I knew what to say to be helpful. And apologies if anything I have said has not been helpful. It is so hard to know what to say to someone who is suffering. My heart goes out to you!
