Two options: 1. I get interrupted sleep of about 4 hours due to bad dreams or anxiety, being unable to fall back asleep for another 4 hours, and then later being overcome with sleepiness and ending up either sleeping too much if I can or trying to get out of bed to carry on with the day, being a total zombie. 

2. I sleep uninterruptedly, but without an alarm I can wake up 10-12h past. With alarm: if I sleep uninterruptedly for 7, 7.5, 8 hours (tried all recommended amounts), I wake up extremely sleepy. Unless I absolutely have to get up (something I can’t postpone), I end up falling back asleep for 3-4hours  of what seems to be light sleep.

I lie in bed for hours and can’t make myself get up even due to feeling sleepy and very tired, and postpone on anything I need to do, even the necessary things. It’s been like that for few years. The fatique just never ends. I barely feel energised. It’s a total joke that no matter how little I do, I’m always so tired as if I worked 24h/day for years. I keep postponing on all activities and solving all the problems my procrastination and fatigue cause. I’m failing at studies. It’s a self-endorsing vicious cycle, where lack of energy worsens problems instead of solving them, which worsens anxiety, bad dreams, depression and sleep problems. 

I used to have vit D and iron deficiencies, but I have been medicating for 2 years for that. Also, I take the multivitamins. So, vit deficiencies aren’t the root cause. The only thing that made me a bit energised was “noopept” (newer version of piracetam) - the only legal stimulant in my country which you can buy OTC (other ADHD stimulants are illegal in my country, and I have ADHD 100/100). But I’m not sure if it’s the effect of the medicine, or because I was taking it at the time when I had deadlines/exams, and had to stay more active at those times.
