First, because you’re still “holding it all together” it may make it harder for both you and others to spot the very real mental and emotional strain you may be under because you pass. You fly under the radar. You and those around you doubt the seriousness of what you may internally wrestle with because, after all, your life still looks pretty great from the outside, right?
Second, as someone who is high-functioning, you may grow up believing that with enough effort and willpower, you can achieve, gain, or fix anything that life throws at you. Not so with high-functioning depression.
High-functioning depression isn’t just a bad attitude, and you can’t just “will your way” out of it. High-functioning depression is a biological and psychological disorder that requires adequate and clinically appropriate treatment. Arguably, the more you push and “will yourself out of it” instead of seeking proper support, the worse your symptoms may get.
