Rest Isn't Enough

Hello readers! I apologize in advance but I'm picking this day to whine!
My period ended a couple days ago (Thursday) and I'm struggling with major big time fatigue and some pain. Let's remember, I work nights now.
No matter how much or how little I sleep, whether or not I exercise, no matter how I eat: I'm exhausted.
I find myself waking up later and later every day despite going to bed earlier than normal. I just can't drag myself out of bed before 1pm.. Sometimes closer to 2pm. It makes me very sad. I no longer have time to do my favourite things.. Except yesterday I did work out for a half hour in an effort to boost my energy levels.
Today I feel completely wiped. I started my treatment Thursday but it won't take effect for a couple of weeks. I'm still in pain even though I really shouldn't be. It's on the right side and it hurts my side, back, and legs. Ibuprofen doesn't touch it. It's difficult trying to focus at work but I'm trying my best. I'm just so sick of this! When will it end? I need to whine because I am sad. I wake up, get ready for work, struggle to stay alert and focused and then I come home and go straight to bed. Nobody understands. I can't talk about how I feel with my family because they just go on about how shitty they feel. I'm not saying they don't deserve to whine either but whatever ails them will go away. Mine is forever. I just need someone to listen and understand. Not put me down or make me feel like I'm being a big baby who should just suck it up. So I stay quiet and vent on my little blog here instead.
Most of the time my family doesn't know what's going on with me. It's because I honestly don't think they care that much? I could be wrong but that's what it feels like. I'm so sad right now :(
I'm just so frustrated with having no energy and being in pain all the time and there's absolutely nothing I can do about it. I don't want people to think I'm lazy because I sleep so much. I want to be back to the way I was a little over a week ago. I had so much energy! Now I'm wasting every single day :(

I'm sorry for the negativity I just had to get all that out.

Thank you for listening.
