Guys, I think you need to realize the difference between depression and clinical depression. Clinical depression is a mental illness, and needs to be adresses with therapy and medicine. The mind simply isn't making enough "happy". Normal depression happens to anyone when something terrible happens. Death, tragedy, ect. But it goes away Clinical depression is reoccurring and debilitating.
I do not think anyone on this forum is qualified to diagnosed which Robbie may or may not have.
I will say this, you can talk on the internet all you want but nothing is going to happen unless someone goes to Robbies house and helps him. If he is depressed, and hoarding animals, someone needs to go over there and HELP him, physically. Help him clean, medicate, move, whatever.
I think someone (or someones) should make a list of people willing to take snakes in temporarily or permenantly to help Robbie get down to a reasonable number, arrange a date with Robbie to clean out his house, buy medicines that can be bought over the counter for mites or whatever else the snakes need, make sure everything is fed/cleaned/watered and pack up snakes to go to foster homes. And get any animals that need vet care vet care. Simple as that.
After that, they can help him get into some kind of therapy to help him with any depression he may have.
Keep in mind, none of this can happen unless Robbie wants it to. Nothing will change if he's not willing to change. Now, I would be totally willing to do ALL of this for someone I knew... but I have never met, talked to, or seen Robbie so it's really not my place. Someone should contact his friends/family and let them know how to help.
