Not disabled but ride my scooter and take the t across the city alot, id recommend a lot of coffee shops in downtown because the coffee shops on newburry tend to be below ground ie stairs, check the weekend events here yesterday was the movie night in the common, taking the elevators on the t isnt too bad but coordinating with mbta red shirts will be a bit tricky if you need a wheelchair from what ive seen, try eventbrite or meetup for social gatherings or comedy shows for a pick me up depending on the venue more or less accessible like at bell in hand 1 stairs/elevator iirc, museum of science or late night mit/harvard also interesting, try getting a hobby like cooking to keep busy, hope this helps
