Sorry you are feeling this way. I understand that feeling I feel like this everyday. Lost and confused, this world is not real. I start to panic and feeling like losing control and I fear more. It's weird feeling. I do suffer from anxieties. Ur mom is right about it's all in our heads. We have chemicals imbalance that makes us think and feel this way. Therapy it's a good way to go. Another thing that helps me calm down is praying and trying not to think about it. The more I think the more it gets to me.. I'm not taking medications. But sometimes I feel like I need to. But I'm hoping for the best. And I really hope you can find peace in ur mind. Try to consider therapy .. I'm 99% sure you are healthy and fine. It's our head that plays tricks on us.
Just for the record, there is no evidence a chemical imbalance exists in people suffering from mental illness. If there is one, nobody's found it yet, though they're still looking. So if there is one, we don't know which chemicals and where they're coming from. As to the post, you say you have derealization and depersonalization but say you havenn't been to a doctor. So I'm wondering, have you been diagnosed by a psychologist with this? Or are you self-diagnosing based on surfing the internet? These terms are labels representing effects of mental illness, but there are a lot of things out there that can be wrong that might feel like those things but aren't those things. You don't say if you've been a long-time sufferer of anxiety or depression or if your anxiety is a result of feeling these things you're describing. So the proper first step when you feel off is to get a thorough work-up from a physician that tests for as many of the things as possible that can cause what you're feeling, such as nutrient deficiencies, thyroid or other hormonal imbalances, blood sugar problems, drug use, sleep disorders, etc. Only when physiological causes are ruled out do you know as best you can that it's a mental problem. At that point, especially at your young age, the usual thing for a doc to do until recently was to send you to a psychologist who specializes in anxiety treatment to see if you can work it out. If that didn't work, the psychologist would then refer you to a psychiatrist for medication or you would try something else, such as lifestyle changes or other forms of medicine, but you'd try something. You're likely to get a few answers on here, and I'd say if you're concerned your parents aren't responding to this with the proper urgency and you need their support to get help, then have them read the responses you get here from those of us who have had this problem a long time. When I was young, and I'm in my sixties now, anxiety and depression were considered by most Americans to be cop-outs and laziness. That allowed them to fester until they were really hard to fix. I woldn't advise that course.
