First I'm glad your cardiologist has given you the ok. I would not split the medication without talking to your dr first. A psychiatrist is better with managing medicines for people with depression or any other mental problem. Most general drs are not comfortable with following up on people with depression, that is not their area of expertise. As for a therapist, mine helps me with dealing with everyday things or things that cause me distress, or family issues. She keeps an eye on how my mood appears and has seen me long enough to know when I am beginning to go up or down and we catch the episodes before they get very far. My therapist has saved my life. Obviously the choice is yours. Perhaps a support group where you could sit in until you are comfortable talking would be a better fit. No one is made to talk, sometimes just hearing others' stories helps you feel less alone. I hope this helps.
