I cringe at the tought of talking to a girl.

I visited a psychologist today for the first time and she said i should do exposure therapy or some shit,the first few weeks and work myself up to being able to actually talk to people.

My goal is to get a girlfriend,but im too scared to even look a girl in the fucking eye.Would it be wise to start conversations with random girls on the street,in a park/mall or will i just creep them the fuck out and in turn get demoralized and the whole thing being counterproductive?
