Guys, I'm so friggin tired it's just NOT funny

I've always needed very little sleep, but these days it seems to be spiralling outta control

4 the last 7 years or so, my sleeping patterns have been very predictable, 5 max 6 hours a night Mon-Thur (which I'm sure is normal) and then 10 hours Sat morning. (it's always been easier for me to fall asleep in the early hours of the morning)

And when I'm oddly depressed, all I can do IS sleep, the times when my mind is racing about how useless and worthless I "am" at the time,and I can't sleep, I take a few sleeping tablets to block out the thoughts...(please don't ask "how many is a few?" Prescribed dosages have never been sufficient 4 me, when I was 12 the Dr was so shocked because he had to inject my EARLOBE 4 times with local anesthetic, when I got a tooth extraction, I needed 3 injections and when I was in labour, I needed double the prescribed dose of pethadine,despite my tiny frame. But I know I've had a problem with pain killers and sleeping pills in the past, so 4 the last 3 years I've been trying to avoid medication. (but when absolutlely neccessary,try my best to stick to the prescribed dosage, praying it will be effective)

These days I fall asleep around 2am, and get up for work at 5am, and Saturday morning sleep is basically out the window...
(I don't wake up tired)

I try not to take the sleeping pills during the week as it takes too long to kick in, and I end up missing my alarm!!!

Right now I literally can't sit still, I'm singing at the top of my voice, and dancing (at work yes...here's minimal staff tight now) but at the same time I can feel my body just wants to go into a coma, it's so CONFUSING!!!
and a tiny bit scary, 2 months ago I literally passed out from exhaustion 3 nights in a row. (I'm not sure how long these 3hr nights were going on before that happened)

How can I be hyper and dog tired all at once, I've been wondering about this for a long time, but never had anyone I could ask this question 2 before... (I've always just thought of it, as me being in over-drive)

Please take into context that I've not been dxd with ANYTHING (appt coming up to clarify my behaviour tho...)

I'm sorry for rambling on and on about something as petty as being tired AND hyper, but as ecstatic as I feel, I'm also irritable, cos I jis wan2 SLEEP!!!! and now I'm rambling for no good reason...

How did I forget to sleep? Is this okay? Not even sure what I think I'm supposed to get out of this post, not suprising as I can't seem to hold 1 specific thought all the way through...
NB. On the verge of tears all day, even tho I'm happy, my 1st reaction is to CRY!!!... why do I get like this, IT'S CONFUSING, maybe I'm just really really tired...
sorry again..
