Its good that you are seeking help. No one should be uncomfortable, especially with the symptoms you have. They are the worst because they mar reality and are very upsetting. It sounds like what your are experiencing is much broader than the symptoms you have. They are merely small insights into what might be a larger picture. Depersonalization and disassociation are ways the mind copes with outside interference, much like the social anxiety. Both are directly related to your fight or flight instinct and the brain is trying to figure out how to keep you safe for some reason. Most illness like this doesn't appear until the early 20s so it might not have been caused by a specific event. More like a series of events over the course of your lifetime and as people age, organically the brain changes. Do not be afraid of medication. I am not a huge proponent of it but it can get you comfortable enough to work at arresting your symptoms. Understand that psychiatry is an art unlike any other medical specialty. It takes more time and effort on both the doctor and patient's part to alleviate symptoms. If it were that easy, message boards like this wouldn't exist. Be honest with the doctor and explain that Celexa did not agree with you and you are sensitive to medication. Ask the doctor what he/she would prescribe as a comprehensive plan that you do not want to be treated simply with medication. Psychiatry doesn't offer all the answers but can provide an avenue to feel better, just be open to what is offered. Leaving your symptoms untreated will only cause you more pain. Keep us posted.
