Part 2 of my phobias as shuffle series! This phobia is Thalassophobia as requested by @thabster88 ! Facts- Thalassophobia is the intense fear of of large and deep waters. This is different from aquaphobia (fear of water.) Symptoms can range from mild to severe, including anxiety, nausea, shortness of breath chest tightness, and trembling. Some people may experience panic or be triggered by even just seeing pictures of deep water.
