I would recommend undergoing a medical, neurological and psychological assessment. You seem to have a combination of both physical and psychological symptoms, the cause of which may be medical or organic in nature.
The best way to address these issues is to do the following: make an appointment with your primary care physician (PCP). Report your symptoms. Ask your PCP for a referral to the appropriate professionals.
Consider involving your parents. Report your symptoms to them and ask if they would be willing to assist you in receiving the proper evaluation and treatment. If they are unwilling to assist you, then go to the counseling center at your university and ask for their assistance.
I’m sorry you’re suffering but it is imperative that you ask for help. There are many treatments available that could address your symptoms. I hope you’re able to seek the proper assistance and evaluation. Please take care.
