If youre exhausted, can you rest? Sorry, I dont know if you work. The reason I ask is because a work schedule can be disruptive to getting the right rest. If you're not working you could be exhausted because your brain is working overtime. Im not sure if your thoughts are clear or not? Are you feeling 'spacey' a lot?

An interest in something will help build up energy but if your at the bottom maybe try and get the rest you need if you can first.
