36 y.o M here. Sorry for my broken/bad English. The past year I've been having many, constant panic and anxiety attacks, especially at work. It's impacting my life. Even with simple tasks I'm often filled with a sense of fear and dread, that something bad is going to happen. Normal, everyday tasks have become a struggle. There's also dizziness and a fear/sense of fainting. Feeling tired and sad. I'm thinking I might be suffering from Anxiety but don't know whether I should visit a Psychologist or a Psychiatrist.  I want to get help because as I said it's having a serious impact on my life and I'm starting to avoid things like going for a walk or swimming because of the fear and dread this might make me feel.  
So where do I start? By visiting a psychologist or a psychiatrist?
