I agree with above - the best thing you can do is to keep a strict schedule. The way I can best explain it is to treat it like a job. Set scheduled hours where you attend classes and set times at home when you sit down and do your work. If possible, get a wall calendar and write on it your assignments and important dates and then work out when you will work on assessments leading up to those dates so you don't get too far behind.

Of course life takes over at times, but if so try to arrange to do it the next day. Eg. I can't do an hour of philosophy as scheduled today because of _______ but will put it in my diary for tomorrow afternoon 4-5pm before I cook dinner.

Just take it slow, and take regular breaks And if needed, use the services out there - disability services and student unions can be amazing supports if you do find yourself overwhelmed. They also often have contact details of other peer groups or individuals who may be in a similar situation to you who can provide more specific support and advice.

Good luck
