I need help. Serious help. I'm not sure if I can carry on anymore. I'm not sleeping at all and I'm unbelievably exhausted. I can barely function because I'm always tired. I'm not eating, loss of appetite and weight loss. My heart rate is so fast I can feel it constantly beating without touching my chest to check it. I'm short of breath and I just can't seem to breathe normally. All i want to do is sleep! But I can't! There is only so much I can take before I will just give up. I'm just not strong enough.
