I'm a mong so can't express stuff as well as other posters have, bear with me.
Psychiatry is like mental martial arts, it's best to arm yourself in defense for people using it against you, which happens all day, every day; from sales to shit on the internet yadda yadda yadda.
Psychiatrists are usually grifters, as most cases of sadness or depression, pop-depression not genuine depression, can be solved in one or two sessions at the most! I know people who just need a slap (I'm not joking about the effectiveness of a physical attitude adjustment) but instead pay £30+ a week to attend councilling.
Psychology, like maff, Iniglish and soyence, should be compulsory learning in school.
Never take meds for mental illnessess, unless it stems from physical brain damage. You cannot cure a mental illness with physical pills. Pills can cure physical ailments like diseases or whatever, but not mental ailments. It's a massive grift designed to get you hooked for life.
Finally, everyone should be told (especially those on the internet) that it's OK to feel sad, down, angry, fed up etc. It's normal. What's not normal is heading to a comfy sofa to talk to a stranger about how you feel sad because your dog died. Feeling sad is a natural process, you have to swim in it, be part of it and in a strange way, enjoy it.
