Hi there,
I hear you, and I would strongly recommend that you seek help with a local doctor who can follow you up regularly. Do you have an in-campus doctor or at the very least a counsellor? At this stage, I think that you need some medication to just boost you a little bit back into function, which is why I recommend going to a doctor first, preferably a
psychiatrist. However, a regular
primary care doctor is also able to prescribe you some short term anti-
anxiety medication that you can take when needed.
On the issue of managing your anxiety long term, I strongly advise following up with a counsellor or
psychologist, who will be able to see how you are doing on a regular basis. They will probably work on methods like cognitive behavioural therapy and mindfulness, which will teach you steps to control your anxiety on a day to day basis. If you are really hesitant on meeting someone face-to-face, there are online resources on mindfulness that you can read up, a prominent one being a course on the online learning site FutureLearn. It basically focuses on how to train yourself to concentrate on the present moment instead of worrying about the future and letting your thoughts snowball into an unmanageable catastrophe.
Your in-campus counsellor would also be a very useful ally to have if you feel like you are at a stage where you can't keep up with the work. Talk to your college administration and see if you can make it up another way, or delay your submission until you are feeling better. A letter from the doctor will also help with your case, and this will take the pressure off you and let you focus on getting yourself back on track for a while.
Don't live in fear, there is help to be found.
Hope this helps, and all the best to you.
Regards,
Dr. Teh
