I just wrote a very long response to your question, but it was deleted accidentally!
I'm a psychotherapist, so I am answering from that perspective.
You might consider asking your doctor or a friend for a suggestion or a referral to a psychotherapist. People who work as psychotherapists can have a variety of degrees or titles. It's important that you feel comfortable with the person, that he or she seems to be wise, experienced, and knowledgeable. Every session with a therapist may not feel terrific, but the overall experience should be one of support and understanding.
It might be helpful to ask if he or she has experience in evaluating for the usefulness of psychotropic medication, what the therapist's attitude is toward medication, and if he or she can prescribe (or works closely with someone who does). It's most helpful to work with someone who's knowledgeable and flexible, who'll listen to your wishes, and can provide you with feedback and information that can assist in your decision regarding the possible use of medication.
Many of the newer antidepressants are very helpful with anxiety, also. If you decide to try medication as a part of your approach to your depression, there may be a period of trial and error until the right medication and right dosage are found.
I agree with the comments above regarding exercise, diet, and support. I'm not familiar with the specific Omega 3 described above (but plan to read about it), but sometimes supplements can be helpful.
It looks like this may be deleted again, so I will just say that you need to be compassionate with yourself. Feeling stuck is not a character flaw; it's a symptom of depression. Good luck!
