SSRI's are known to increase prolactin creating the problem you just described, lactiting nipples AKA prolactin gyno. The reason being is that SSRI's increase synaptic serotonin levels which has an inhibitory effect on dopamine thus increasing prolactin. This is also why SSRI's can cause sexual dysfunction, due to the increase prolactin levels.
What to do? You don't have to get off the SSRI, rather introduce Pramipexole (another DA agonist can work, Caber for example) and not only will it reduce prolactin, it will compliment the SSRI and actually banish a lot of the sides from it. Pramipexole itself has been trialled as an anti-depressant and used in combo with an SSRI. Expect your libido to come back and your mood to be far better than the SSRI alone. 2x daily dosing of Pramipexole would be best, AM/PM as little as .125mg 2x daily, optimal results would be from .5mg to 1mg ED.
