Since yesterday I have felt completely tense and feel like I am going to burst (metaphorically). Had a headache last night at bedtime and took a couple of paracetamol then lay awake getting really agitated until 2.30am. Fell asleep and had horrid dream and woke at 3.30 feeling scared as I had done in my dream. Obviously then woke this morning completely knackered. Ive got myself really mithered about my potential unfair dismissal claim and really need to know how to relax. Help.......
