How can I trust a therapist to help me?

I have psychological problems, and I probably need help. However, I have a negative view of the mental health profession in general due to bad experiences in the past. It bothers me that therapists are educated in modern universities where all forms of leftism and equally irrational psychological theories predominate. In my state, many licensed "counselors" are just social workers (the most leftist whackjob profession of all time) with government licenses to counsel people. I am afraid that they will have me involuntarily committed if I am honest about my thoughts of suicide, which I have ready plans to carry out if I decide to. How can I trust anybody in this [expletive deleted] profession?
