Hi,
SW here - I had a medical linked to my BA degree - so I can't see this being an issue for you re already being accepted onto the MA and I have not had any medical, nor can I really remember being asked about anythig relating to my health.
This would be entirely up to you, but you could share this with any future manager, just to make them aware and for them to support you during any time of stress! But this would be at your discretion!
I think the only concern would be any ongoing mental helth needs, and if this was to have an impact on you doing your job safely.
