These can be symptoms of depression yes. Loss of concentration is definatley a symptom of depression. You are on a low dose of fluoxitine and have only being taking it for 3 weeks so it may not have properly kicked in yet.
The usual starting dose for fluoxitine is 20mg but some doctors prefer to start on a lower dose and build up.
I think you should maybe go back to your doctor and explain how you are feeling and the comments that people have made about
your concentration and see what he says. He may increase your dosage slightly. One the medication starts working fully you should start to notice a difference in yourself but unfortunatly it doesnt happen overnight.
