this advice is not from an expert like a doctor or a therapist. this is the advice of a non expert. this guide comes with no guarantee about how happy you will be. you are responsible for your own happiness
some unhappiness is caused by chemical imbalance in the brain or by external circumcstances not to do with outlook on life. if you think you may be chemically imbalnaced or need some real professional help seek a real medical doctor. if you are in a rough life situation where people around you are bullying you seek other info on this site to escape your abusers.
if you are being abused or if your brain is chemically imbalanced, then regular advice isnt going to be enough to make you happy. if you do not have access to a doctor or the desire to see a doctor one of the best ways to handle chemical imbalance is to eat a properly healthy diet. however eating properly is not necessarily going to help a genetic chemical imbalance in the brain.
there is nothing wrong with admitting if you are unhappy. there *is* something wrong with being unhappy and not admitting it to yourself. you deserve to seek happiness.
there is zero guarantee that the advice that society gives you is going to directly lead to happiness. in fact it is the opposite. most of the programing from society is designed to make you useful to society and to fit in to society, not to make you happy.
