First, psy-vamps don't pull out "all the positive energy"...they take energy period, they're not capable of picking the pattern. Whatever you have, that's what they take, in the same measures.
Yes, if your energy is drained below a certain point, it can cause depression and immune system reduction, as a temporary effect, until your energy level rises back to normal levels.
Most psychic vampires these days do not do this as a matter of course, if they are aware of what they are doing. In fact, there is a movement in the psy-vamp community toward consentual feeding, meaning they only take energy from those who they have specifically asked, and gained consent from. It's an ethical move that should be encouraged, IMO....in other words, don't condemn all psy-vamps without regard to their behavior, and don't ostracize them....if you cast them out, why should they care about you?
Now, if someone does try to drain you, in the vast majority of cases, they are not going to be looking for a fight. A sharp tug back on the link, then release, is enough to cause most of them to give up and seek elsewhere. It lets them know that you are aware of what they are doing, and will put up a fight. A tug of war is just as uncomfortable for them as it is for you, whether they win or not...it's not worth the effort when easier targets are around.
In the case of a deliberate vamp attack--that is, the person intends to hurt you by vamping, they're not merely after your energy--then other tactics are in order.
Most of these tactics require a fairly high amount of knowledge and experience with energy working. If your shields are not adequete to prevent vamping, and pulling back does not work, you can attempt to overload them by rapidly changing the speed of the energy flow. You may also try throwing earth energy into the link, or grounding the link to a ley-line, then blocking your end (ouch).
By all means, attack back--if you can hurt them, they may just decide to give it up as a bad job.
