anxiety,light intensity and parasites

Hi, For the past 3-4 months i have had unbelievable anxiety. When it began i was having about 3 panic attacks a day. For the past 4 months colour have been so intence, and I have become really sensitive to light. I have gone between extreem Depression and anxiety... as well as having little spurts of paranoia.... I decided to go the holistic route.. and working with my naturopath, i have found that i have parasites, as well as a heavy metal overload... I have been taking anti parasite herbs for almost two weeks... I had a couple questions that I though the group here might be able to answer.
First was i have not seen any parasites yet in my stool.. but It has turned a strange green colour ..what does that mean?
also i have been super constipated, and i have tried seens, cascara, triphalla... Epsom Salts , fiber.. and nothing has kept me regular... my symptoms get wayyy worse when Im constipated.. so if anyone has found something that helps..please let me know.
I also wondered if anyone else had such extreem reactions to parasites (panic attacks, depression,paranoia..and light intensity)... I have felt just so totally screwed up... always bloated , waking up in rages... crying fits... I am so happy i am on my way to health!
Thanks for your help
