I am so there with you. It seems like the fog will never lift. I myself am going through a lot right now. We can't let the depression win. I come here to PsychCentral so I don't feel alone. There is always someone with a kind word and good advice that will help me make it through. Use this as part of your support network.
Your blood pressure being high is not a good thing. If your doctor is not helping maybe you need a new doctor. Have you made changes to your diet? Could one of your other medications being increasing your blood pressure? Your medications can also be making your depression worse.
I hope things get better!
