Hello, The symptoms that you have described are due to anxiety. There are different types of anxiety disorders such as panic disorders, obsessive compulsive disorders, post traumatic stress disorders, social anxiety disorders, generalized anxiety disorders and specific phobias .It is a mental illness and the patients are usually constantly worried and fearful which could be crippling .In your case, you had a panic attack and a weird feeling which is quite common in panic disorders. In addition you have been taking Setraline 25 mg a day for the last three days. Setraline is a selective serotonin reuptake which produces drug interaction .It produces a longer lasting active metabolite and the usual daily dosage is 50 -200 mg per day .So the dosage that you are presently on is quite negligible. However if you are still experiencing some discomfort, I would suggest you to consult your doctor. Thank you.
