I Am 66 Yrs Old, I Take BP Meds BP

I am 66 yrs old, I take BP meds BP diurects,and Zoloft. Also fish oil ,garlic D3, B12. I am very, very tired, this started month ago. I have been sleeping lots. My Zoloft is working well, I'm not depressed, but I am so tired. It's christmas there is so much I want to do, but no energy. I also have hives, that really itch,but they don't look bad.they are on my neck,back , tummy. Should I cut back on Zoloft? Or diurects, maybe take potassium?Or maybe BP med too much. I have been on BP meds and diurect and Zoloft for 20 yrs.
