Hey. Sounds like you might have Gallstones and maybe adrenal fatigue. Look into it. I recommend "The Amazing Liver and Gallbladder Flush" by Andreas Moritz ; and Adrenal Fatigue by Dr. James Wilson. When your girlfriend left you endured a lot of emotional stress so your adrenals gave out. Also I just finished the gallstone flush and passed hundreds of them. Oily forehead and loss of hair are some of the signs of Gallstones mentioned in the book. I also feel tired like you, mainly in the afternoon but not in the morning or evening (or night). I am still figuring out what is wrong with me but definitely Gallstones need to be flushed out and try to make steps to improve your gut health (colon hydrotherapy, parasite cleanse, probiotic foods and supplements.)
