@Lex I don’t want to be overly critical, but I’ve never been a big fan of the phrase “don’t think about it that much”. It’s like saying to someone, don’t think about purple elephants and expecting their mind to go blank.

It’s not what you think, it’s how you feel and react to what you’re thinking. You can’t always control your thoughts which are simply reactions to the stimulus around you, but you can control what you do with those thoughts, how much emphasis you put on them, and what meaning you attribute to them.

Also, trying to choose between positive or negative thoughts will simply keep you spinning in circles or riding a roller coaster of emotions. Choose neither positive or negative. Instead, strive to choose to accept reality in all its current forms and future possibilities.
