Do not try to solve problems in your bed. Get up. Turn on the light and describe your problem on paper. And go to bed again.  Your brain forgets what is on paper.

Solving problems is easy and interesting and all problems can be solved! But, do not try to solve several problems at the same time. That is impossible. The best way to solve problems is to list your problems on paper (do not overload your brain with all kinds of problems). When listed on paper cut each problem into small pieces. Start finding out what caused the situation you are in/your problem and then start to write different ways to solve each issue. It then becomes much easier. Question: Are you able to eat an elephant: yes, it will however take a couple of years, but just start with the tail and go on from there. It is the same with problems: cut each problem into small units and solve one part at a time. Easy.
