What are some strategies you could use to get past these barriers? Financial barriers: this a common barrier because not everyone has the financial stability to pay for professional mental healthcare. So, having no money to get professional help is a barrier.
Mental health education: this is another common barrier, because in many cases people don't realize that they need professional help to seek mental health. Actually, the fact that mental illness cannot be seen physically, like other diseases, people tend to ignore it. Similarly, the lack of education in this context is what makes people to ignore this situation, as a result, they don't look for any professional help.
Social stigma: social stigmas tend to influence a lot on people, because they rejection of society is not acceptable for us as social beings. We could define stigmas as negative connotation of mental and emotional issues. One example that shows this is the thought that "if I got to the psychiatrist, that means I'm really messed up", that's one of the social stigma, in many cases people don't look for help, because their social circle would think they are messed up.
These three barriers are the most common, and most powerful, because it's really hard to break them. These barriers are external conditions that influence too much in people's decision at the moment to look for help to improve their mental and emotional health.

Specifically, the barrier that influence the most is Mental Health Education. Due to the lack of proper education about this subject, people tend to perceive negatively this problems, and they don't give it the importance that it should have.
