the best way to overcome trauma is to meditate and tell people. when you tell people you let all the negative feelings out of you and whats left is just a memory, although that memory may scare you you will feel better. this is because if you keep the negativity  bottled up it affects how you act, and that might make people afraid of you so you feel alone and things just get worse. also meditation works because it relaxes you. as we saw in gringolandia Marcelo started to get better after they went to beach and he continued to get better as he continued to go to the beach.
