Suck the life out of me!

So another day of feeling like complete shit! It's miserable, and I'm losing hope in life anymore. This feeling has sucked the life out of me. I don't know what I enjoy doing anymore. My life is a blur. I just wish I could wake up one day and feel better. This is not fair. I've never done drugs, or drank in my life. So why do I have to feel like this? I'm weak, my vision gets fuzzy. I don't feel real sometimes. It makes me have anxiety, and nobody understands. I've passed out twice within 2 years, the last time was just a few months ago and since then I keep feeling faint and can't do things that I use to enjoy doing. It's hard to even go to the grocery store and I can't even go shopping so I do most of my shopping online and send my friends to the grocery store. Thank god for caring friends! I've told many doctors how I feel and they can't seem to find anything, what they do find is little things. So far I've had  different blood work done, and MRI of the brain and MRA of the brain, and EEG of the brain, and EKG of the heart, A ultra sound of the heart and arteries and what did they find? I had PVC which is a heart thing, basically it's not a big deal, they found a cyst in my sinus, they found a narrowed artery in my brain which I was told to take baby aspirin everyday to lower my risk for strokes. Other then that the test were normal. I do have Graves Disease/ Hyperthyroidism which was found a few years back and I've been taking medicine everyday for it and so far its been under control. The doctor told me that since my blood levels are normal I shouldn't been feeling bad, and that something else was going on. However, they can't seem to find anything? The doctors all say its anxiety. My boyfriend, a few friends, mother think I'm going crazy and that the dizziness, and fainting spells are basically all in my head. Which this is my body and I know how I feel! I know I have anxiety on top of this. I know it doesn't help and I wish I could get it in control. It just sucks, a few weeks ago the doctor prescribed me Zoloft but I haven't taken it, I lied to my mom and told her I was because if not she was going to kick me out of her house. The truth is I'm terrified to take the medicine. So I don't know rather it would actually help me or not. I don't know, but I'm tired of feeling this way. I don't know whats really wrong I wish I did. I do try to eat right, sleep right, and exercise right but its not working. I'm losing hope. I feel like a basket case anymore. I don't want to feel sick and tired all the time. I'm not able to enjoy life, people. There is so many things I would love to do but I can't because I feel this way. I'm so scared of life. I'm so scared of how I feel. I just wish I could fall asleep one night and wake up and everything be better. I sometimes think that will happen, but it doesn't . I even think sometimes maybe I can cry the pain all out and I will no longer hurt, be sick but that doesn't help either. It's not fair to me! I'm sick of it. I just don't know what to do. With feeling like this and also having anxiety on top of it. I'm not myself anymore I use to be such a happy person. Now I'm just like this rock that just sits on the computer all day. I have no life. I just don't know what to do anymore.......................I go to the Doctor tomorrow and I'm already scared about that because I'm afraid I will faint at the Doctors office, which if I do I guess that's the best place to do it. I'm just scared. All I want is to be better. What will it take? Well anyways I'm off to get some sleep soon. Night everyone
