Many newly admitted students push asking for disability accommodations far down their to-do lists, choosing to focus on the logistics of moving and settling in. This is a mistake.
The best time to start the accommodations process is now. The process will be slightly different for each law school, but no matter where you attend, the earlier you start the process, the more likely you are to succeed at getting the supports that will help you rock your first year. The last thing you want is to worry about whether you should drop out after finals because of a problem that would have been moot if you had the proper supports in place.
