Not true if you have trauma you are not choosing to have those problems. They could also be things in your environment that are traumatizing you. Things you can't control. Some anxiety and depression is caused by a problem in the brain due to chemicals that are out of balance. And yes meds help, but most of the time the chemical imbalance causes you to stick to a certain way of thinking based on how it makes you feel. In this case its anxious thoughts or depressive ones. And your neurons are soo used to thinking this way that even if your chemical imbalance is fixed you still can't choose to stop thinking that way. It is muscle memory. That's people who are suffering from anxiety or depression based on trauma alone still need therapy and can't just "let go". If your in a pattern of thinking for too long your brain gets used to it and just MAKES you think that way. Our brain is a muscle and it works like a computer. If you keep thinking a certain pattern of thoughts continuously its like a program being installed in a computer, and it will start running. Your brain starts running that program based on things that "trigger" it, hence why people get anxiety over specific things or certain things cause anxiety attacks. Your brains muscle memory us running that program based on something that seems to relate to what thought the program has. If someone is prone to depression because of trauma and you talk about similar problems and how those problems can't go away, the other person will think about their problems and that they will never go away, on impulse. So saying the sun will still rise yadda yadda and the world still moves on is not gonna help someone with these problems. Maybe specific people but not in general.
