welcome to neurotalk. glad you're here!
there is a service dog sub-forum under the 'our pets' forum which might interest you. you can absolutely get a dog to help you. i think that is a wonderful idea.
dogs are here to teach us about love. unconditional love. and so much more. they are so other-directed, too - probably the only creature on earth who will love you more than he loves himself (or herself, as the case may be...)
i say go for it!
good luck
wish i knew how to post that link for you but maybe someone else will come along who can help with that...
