An inquest heard how Lorraine McMullen feared she was about to develop dementia after reading it was common in people at that age who suffered from a thyroid problem.
The mother-of-two, who was said by work colleagues to be a happy and fun member of staff at Fulwood and Cadley Primary School, kept her anxiety and depression secret from those outside her family.
"(To everyone) She was such a happy outgoing individual," said husband Steven McMullen. "She was like that when people were there, but when she was on her own she was down.”
"She spent her 55th birthday in bed. She wouldn't open her cards or look at anything. She just ignored it."
Mr McMullen found his wife dead in the shed of their home in Blundell Road, Fulwood three days later, after he had return from walking the dog.
Former pupils and those connected to the school were among those paying tribute to Mrs McMullen.
