being able to let things go, would be firstly, forget about whatever may be on your mind, mentally, bills, kids, whatever. Tell yourself, that you have a solution to every problem, and each problem is solved. Instantly, your high (endorphins), should kick in.
Secondly, if you have some issues, abt your partner, ANY. Tell yourself, that he is the last gunslinger on earth, and that you are so very lucky, he's choosin you, the princess.
Talk stuff in your head, or to him, "baby, I know you love the pretty dd"s", cause even if they are less than perfect, saying it aloud, in the moment, melts doubts and fears.
Appreciate the things U like abt your man, for me it's his chest, his little bird legs, are a little less flattering. But I'll mentally tell myself something positive, abt those lil bird legs, like, they full of muscles, they work so hard for me and my family.
Turn negative thoughts into positive ones.
Then, BAM!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Real talk, thats the business.
