Yes, it is possible that you have been misdiagnosed, however, that is difficult to determine from a short letter. My main concern is that you may be experiencing the prodromal phase of psychosis. The prodromal phase can be a one- or two-year period (it varies for each individual) that precedes a full-scale psychotic episode. During this time, an individual begins actively experiencing symptoms, such as difficulty making choices, anxiety, or problems with concentration and memory. Some individuals also become isolative and have problems communicating and interacting with others. During this phase, an individual’s symptoms are noticeable but usually are not severe. Typically the symptoms become increasingly worse over time. It can be difficult for the individual experiencing the prodromal phase to be fully aware of what is occurring.
Yes, there are free ways of accessing mental health treatment, especially in a university or college setting. College counseling centers offer these services to their students. Other ways of accessing free help include: (1) going to a local community mental health center; (2) calling your local health department and asking for a referral for free mental health services; (3) or going to a local psychiatric hospital and inquiring about free or low-cost services in the community. Given your situation, the college counseling center may be your best immediate option. I would specifically recommend seeing a psychiatrist for medication. If you are in the prodromal phase, medication could avert a possible psychotic episode.
I would also recommend contacting your parents. Make them aware of your symptoms. They may be able to help you access treatment. At this time, it would be advantageous to have a trusted friend or loved one assisting and guiding your decisions. Your symptoms may interfere with your ability to think clearly or to make the best choices.
It is imperative that you seek help sooner rather than later. I would advise being less concerned about a specific diagnosis and instead making it your goal to seek immediate treatment. Treatment, specifically antipsychotic medication, may have the power to prevent a psychotic episode. Research consistently shows that with regard to psychotic disorders, the sooner one seeks treatment the better the prognosis. The importance of seeking immediate treatment cannot be underscored. I wish you well. Please take care.
