I know that there's something seriously wrong with me, and it's upsetting me so much. I have constant symptoms that make me feel ridiculously ill and my pulse is constantly ranging from 55 to 130 at rest. Walking upstairs, laughing, getting angry/shouting make me so breathless, exhausted etc and make the feeling in my chest so bad that I have to clutch it. Right now I can feel my heart beating in my back and I have such a bad ache down my left arm from my neck/shoulder and head. I'm exhausted constantly, even though I get 8 hours sleep a night. It's like this constant lethargic, sleepiness that makes it so hard to keep myself awake. The waves of tiredness come over me suddenly and I can physically feel them come over me. Most of the time my breathing feels really weird, like there's not enough breath when I'm talking etc, as if my lungs aren't working properly. I am so detached today and feel barely with it. It's taking me so long o do anything - last night it took me 3 hours to plug my phone in to charge as every time is picked it up from next to me, I got distracted and forgot about it. It's like I'm so sleepy that I'm not with it and don't know what I'm doing half of the time. I feel so dazed and spaced out, like I can genuinely feel myself slipping away. I'm only 19 and I'm so young and all I want to do is live. I don't understand why I have to die young when I don't want to :(
