What Causes Severe Cold With Loss Of Energy?

It s been a recurring thing that I ve always been cold or felt cold. Even if I ve got more than enough layers on, I m still really cold. I am a very pale person, there have been multiple times when I ve been asked if I ve felt alright because I ve looked so pale. But also, I always seem to be quite tired the majority of the time - I just feel so drained of energy and I think it s due to the fact that I struggle to sleep at night. If I do manage to get sleep, when I wake up there s this feeling of weights on me, as if something is pressing me down. -Thank you for reading this
