This is lowkey a touchy subject. All people have different point of veiws on the subject. When you dont talk about things and you keep it in, it only gets worse. The key to meditation isnt to clear your mind, its to let your thoughts flow. Thats helps clear your mind. When you keeps secrets you expext people to know whats going on and for them to treat excactly how you want them to. In reality it doesnt work like that. People on the outside have no idea and it hurts both partys. If you have had a traumatizing experiance in the past then dont hold it in an let it get worse. Find someone you trust or someone that trusts you and just retell the story, dont hold nothing back and just let it flow. It will help you mentally and make you a happier person.
