If someone has a physical illness people understand that. Its ok if you tell people that you are going to the dentist because of sore tooth or you are seeing a physio due to a bad back but the moment you tell people you are seeing a psychologist they tell you that they are sorry or look at you as though you will fall into a million pieces right in from of them. It shouldn't be a big deal, mental illness is no different than a physical one just that you can't see it. The brain controls everything and if that's not healthy then rest of the body begins to suffer, so in reality shouldn't it be ok to talk about mental illness more than physical illness?!
Its ok to ask for help when you have broken a bone or need support doing tasks due to not being physically able and its ok to ask for help when you feel as though you are falling apart and don't know why, either ways its ok to ask for help when you need it.
