Here are some misconceptions that lead to stigma in mental health.
Mental Health functions in a similar way to physical health. It requires preventative care, treatment and maintenance in the same way our physical health does. While not everyone will experience a mental illness or disorder, everyone has mental health.
In 2020:
1 out of every 5 adults in the US experienced a mental health condition
1 out of every 6 young people in the US experienced a major depressive episode
1 out of every 20 people in the US lived with a serious mental illness, such as schizophrenia, bipolar disorder, or major depression
Mental health struggles can have many causes none of which mean you are weak:
Biological factors, such as genes, physical illness, injury, or brain chemistry
Life experiences, such as trauma or a history of abuse
Family history of mental health conditions
Mental illness can be treated at any stage with a variety of treatments. You can reach out to a professional the same way you would if you had a physical illness.
Not all therapist will be a good fit. The therapist you choose may have certain experience and attributes that can increase your confidence in them. Maybe they have experience conducting therapy in Spanglish. Maybe they have experience treating a mental health disorder that you've recently been diagnosed with. Maybe they have experience working with teens who are struggling socially. Look for someone who fits you and your families needs!
A therapist should never tell you how to live your life. Their job is to help you make decisions and gain insight that you feel will improve your life. The therapeutic process should feel collaborative and you should be in control of your care the entire time. If you start to feel uneasy in this regard, you can bring it up to your therapist. If you aren't able to get on the same page, you may want to consider seeking care from another professional.
In almost all cases, it is unnecessary to tell a client they are wrong/right. Couple and family therapists are trained to "view the relationship as their client" in order avoid taking sides and having bias. They may also get supervision and consult with other professionals to make sure they are maintaining ethical practice.
You are absolutely right! Therapists DON'T have it all together. That's why they go through significant training to make sure their stuff doesn't interfere with your stuff. Your therapist should be well-versed in how to behave professionally, make sure your needs come before theirs, and center you as the expert of your life.
