Am I depressed or suffering from Anxiety attacks?

I have been doing some research. Today, I am at my wits end and I am really scared. I have not been  able to sleep good at night. I spend my time watching tv all night long. I have had maybe 10 hours of sleep in the last 72-80 hours. I have been having a lot of pulsations feeling in my head and chest, shortness of breath at times. With the exception of today, I probably sleep 20 out of 24 hours.  I can walk upstairs to my bedroom and be completely out of breath. I have been experiencing some numbness around my lips, no energy, no initiative to do anything. When I do sleep, I will sleep probably 24 hours or so. I am in no way leading a normal life. I was diagnosed with high blood pressure. I am struggling with menopause due to my hysterectomy.  Therefore, hot flashes comes so often that I have become so irritated. I wake up drenched in sweat. Once I wake up from the sweats, I'm up. I have been over indulging in chocolate, this triggers hot flashes as well. As I type, when I move I feel the pulsation in my head and chest.  I moved almost three months ago and have not completed unpacking boxes. I have no energy to do anything. I laid here in the bed and just cried because I know that something is going on but I don't know what.

I feel terrible. I am normally an outgoing person that thrives off of helping others. I do not have the desire to do what I do best. I feel like I am neglecting my family because of all of my issues. As I was walking upstairs, I felt as if I was going to fall backwards and that concerned me. I am always tired and have no energy. If I am lying down and move slightly, I feel the pulsations.  I was hospitalized for this in December.  A complete work up was done on my heart and all reports came back clearing me of any kind of heart diseases. Only High Blood Pressure.

My medications consist of: Effexor given to me to control my hot flashes. Cozaar Atenolol and Adalat taken for High Blood Pressure. Aspirin as a blood thinner. Black Cohash to control the hot flashes even more. I put myself on B-12 for energy. Calcium, Multi-Vitamin for women, Fish oil and Flax Seed Oil. I was taken Premarin but I was afraid of the cancer scare if used for long term purposes. At this point, it feels like nothing is effectively working for anything.  I am very emotional and take everything to heart. I have distanced myself from people and the things I love the most.

Up until this point, I have led a normal, health and active lifestyle.  I want this lifestyle back.  Please help me.  Is there an cure for these pulsations that's happening so often.  In one week, I have gained 3 pounds in my over indulgence of chocolate. I have never had a chocolate fetish before.  HELP
