I agree with traveling lady. It's strange even for someone severely depressed to play with a doll. There is probably a whole lot of underlying issues contributing to this.

See a therapist but see a psychiatrist as well on the side to see if there's anything he/she can prescribe. The psychiatrist can also give you a basic mental evaluation. If you are being prescribed a benzo, Effexor or something like that just say no until you get a better grasp on what you are dealing with.

And yes, treating ADHD is extremely expensive for most people if they don't have insurance.
