Struggling to Cope Without My Safeguarding Teacher

im so so tired i left secondary school in 2020,when corona virus lockdowns started in the uk. its almost been 3 years and i cant let go my favourite person, a safeguarding teacher who looked after me when i was unwell, isnt around anymore i still have her phone number. but i feel like i cant contact her and even if i did it would probably be weird to and i just cant cope wirhout her. she was the only person who understood and cared about me. like genuinely cared. i feel so alone and helpless and pathetic. i want this pain to go away so badly. but what i want more is her. even 5 minutes. or a hug. i cant cope on my own
