Yes. You should never try to diagnose a mental disorder on yourself. You either think you don't have one when you might have one or two, or you might convince yourself that you do and then make it reality when you really never did.
You do not always need a psychiatrist to prescribe medications for psychiatric illnesses. Many family practice physicians prescribe these types of medications. They can prescribe medications that can help relieve anxiety or depression. This is quite common.
