Given that you were employed for a term at your new school, I've known negative references be overlooked on the basis that in the classroom the teacher was doing well (even just doing ok is enough if the school has recruitment issue).
So the fact they have ended your contact, I can see this is serious.
OP - Get out of teaching and do something else, at least for a while.
If you value being in education you could consider TA, HLTA, office staff, school manager, science technician, school/uni librarian, work in a college or university, admin at a college.
You would be surprised how much grace is given for a face an institution knows. Get your foot in the door with a temp non-teaching role. Work hard, keep your head down until it's a permits to job. Then offer the odd supply shift as a teacher when needed. See what happens.
Our school had a DT technician who did exactly that. Ex-teacher who hated the stress. Got 2 terms as DT tech, made permanent tech. Worked for 5-6 years then started doing the odd lesson on supply basis. Then became DT supply cover full time. Then fully employed as a teacher again.
