If you're not due to be up at this hour, early waking can be a sign of clinical depression.
How do you feel about asking your gp to prescribe a short course of antidepressants such as Setraline and for a referral to a therapist/counsellor to help you process the aftermath of past childhood abuse which is having negative impact on your present life? Save the fine detail until you are in the sanctity of the confessional, as it were.
You could also ask for sleeping tablets to get you through this period of disrupted sleep, but before you go down that route I would suggest you try a couple of natural remedies that may help lift your mood and ensure you get a good night's rest.
Imo everyone in northern climes should supplement their vitamin d intake during the winter months and this little spray works for me is frequently highly recommended on the General Health board. Keep it by your toothbrush and use it daily - it tastes minty and will last several months: www.hollandandbarrett.com/shop/product/betteryou-dlux-3000-vitamin-d-oral-spray-60012895?skuid=012895&&utm_medium=cpc&gclid=CJaptufzldACFRa3GwodDGMIuQ
I also suggest you rub topical magnesium oil into the soles of your feet before you go to bed. This will only take a couple of minutes as it's non-oily and quickly absorbed. As a bonus you'll find that hard skin and night cramp (if you suffer from these afflictions) will be a thing of the past and, apart from being an aid to restful sleep, it works wonders on aching muscles/joints, thread veins, wrinkles, and keeps bowels regular.
Replenished magnesium and vitamin d gives us the feelgood factor we get from spending a sunny day at the beach and dipping our toes, or immersing ourselves, in the magnesium rich sea but, as all magenisum oil is not equal, you need to purchase from a reputable source.
I buy both of these products - and use them religiously - on eBay for considerably less than H&B prices and will be happy to give you the details of my suppliers if you pm me.
I know I've been hard on you, but it was necessary to hold a mirror under a harsh light to give you the wake up call you need to call a halt to the destructive behaviour which abases your true nature as much as it abuses your h.
You're not irredeemable, OP, and counselling should enable you to realise that you ARE more than good enough to overcome those demons that are dead and gone and only need laying to rest for you to become all you were meant to be.

I wish you well and, once again, hope that you'll be back with a positive update.
