I am 23 but my body is really not letting me live a happy fulfilled life. I have an autoimmune disease already and I have a feeling my thyroid isnt' very good. I'm very cold all the time, my body aches all the time too. My joints (especially my knees) often feel heavy. I have a very low mood and quite often get upset over little things (like if someone has eaten some of my food from the fridge I will be really upset for about half an hour and I know its irrational). Lately I have been getting very dizzy and I have to make sure I have food with me otherwise I start feeling faint, I have fainted in the past a few times but this feeling of being week has become worse for the last 3 weeks and it is really quite scary. Before I eat I start feeling confused and things don't seem to logic, this is when I make myself eat because I know it'll get worse (im a healthy weight not anorexic or anything and not overweight), after about 30 mins of eating my brain will work again but its worrying as to why my body can't seem to cope. I just feel like i'm deteriorating. Since the start of this year I have been constantly ill with either a cold, flu, norovirus or a bladder infection. I just wish I could feel normal for once. some days I just feel like I don't want to wake up in the morning.
