Hi, I'd like to help you with your question.
A psychiatrist is a medical doctor that specializes in mental health evaluations and medications. Although they can treat you through psychotherapy, it is usually better to see a Master's Level therapist for your talk therapy.
A therapist is a person who has a Master's degree. The initials you see after a therapist's name are the following:
LSW- a licensed social worker. They are trained in family and social therapy.
MSW- the same as above without the special license
MA- a Master's in Psychology. They are usually trained in theories of psychology.
M.Ed- a Master's in Counseling. They are trained in counseling methods and community counseling.
An LSW is fine to see for therapy. Keep in mind that finding a therapist is much like finding a doctor, you may need to try a few before you find one that you feel comfortable working with. If you should need another therapist, here is a link to help you find one: http://therapists.psychologytoday.com/rms/.
Also, you can supplement your therapy with self help at home through books and reliable on line resources. Here are some to help you:
