Mental Health is basically what’s on your mind. It is an umbrella term for your thoughts, beliefs, fears, opinions, doubts, feelings and emotions. If any of these cause any difficulty in your functional self or in your day to day life, any thought or event that’s constantly causing you discomfort, you need to talk to a close one or maybe seek for help.
Your first step should be to communicate what’s troubling you to your confidant or anybody whom you’re comfortable with. Communication is the biggest trick. It helps a lot. Moving forward, seek help from professionals as different things work for different people.
There can be multiple causes for mental illness – biological causes like inheritance & genes, life affecting events, traumas, social stress, childhood challenges or struggles, etc.
