Attachment issues with teacher

i have attachemnent issues with this teacher at college because of trauma and stuff and my parents thinks its crazy but when ever she isnt in my mind goes to a dark place and when she is in i feel safe and it is effecting me and I know there are bounderias but like other ppl go more personal then me sometimes with her and others tutors and then she is the reason why i am at college bc she understands me and when i was in connect to college week last year i was very nervous and non verbal and she was the only person who understood and at SafeDriveStayAlive last year I had a bit of  a meltdown and then an LSA (learning support assistant) took me out and then it was the end and then she saw that i was a bit upset and she calmed me down a bit and when i have thoughts about SH and dark thoughts and then she smiles at me the thoughts intsantly gets rationisled and i try to explain that to my parents but they dont ever listen and then she taught in a special needs school so she understands the way my brain works. I am going into level 3 animal management (Alevel equivelent) soon and i am terrified cuz it will be another transition and change and when there is a change im prone to running away from college or just hiding in a corner or in the bathroom and im also anxious about attending lessons becuase lessons for me are quite overstimulating even tho i have ear defenders and im worried that ill just walk out or not turn up and the teacher hates people missing her lessons but i still am attached to her and then we have lanyards at college and then sometimes i forget mine so i have to get a temporay one but i keep on loosing and forgeting the tempoary ones and then my tutor this year hasnt brung it up with me but even tho its been brought up with him but im nervous about going into level 3 animal manegement cuz last year my friend got lots of disaplinary actions and i also cant cope with lots of people and then in the lessons in level 3 their is like 30 or more people and it is making me freak out. But then some of the teachers at college say 'im not autistic enough' and 'im too autistic' to go onto level animal management and thats what my parents say is well But i also need the level 3 animal management go on the zoo manegement degree course to become a zoo keeper and then some of the teachers and my parents are saying the same thing as like 'im too autsitc' or 'thats isnt for autistic people'  and then the teacher who i have attachement issues with is the only teacher and person who is supportive of me going into level 3 and become zoo keeper. Some of my friends (i havent got that many ive only got 3-4) they are being supportive is well
