An accurate and timely diagnosis makes a much larger impact than most people may anticipate.[3] Often, people who are experiencing symptoms will try out numerous types of therapy, support, etc., for many years without significant progress made toward improving their circumstances, often due to an underlying cause/theme not being fully diagnosed and/or treated.
To be truly effective, the evaluation process is ongoing, not a single occurrence done once at the beginning. As treatment moves forward, new patterns can emerge and things can become clearer. When that happens, the approach can shift with it. The goal is to make sure treatment stays relevant to what you’re actually experiencing, not just what was initially assumed.
Part of the therapeutic process is to help the individual identify and become willing to change their patterns by way of developing new tools to cope with difficult times as they arise, slowing down to develop more self-awareness, etc. As you remain committed to your own changes, they will become part of your skill set, ultimately making everyday living manageable.
