A huge reason why I love Ratchet so much is because he helped me get over my fear of doctors
No medical trauma or anything, I just had an innate fear of the doctors or any medical places at all for that manner. For YEARS whenever I had to go to the doctor, I would feel this horrible sense of dread or I would be worried the doctor would hurt me for some reason (again, don't know what caused this fear haha).
But then I started to imagine Ratchet being the one to check me out, or do any procedures, or prescribe me medicine, ORRR be the one to take care of me after any procedures. After each dental procedure I had last year, I would imagine it was Ratchet himself taking care of me. Shit low-key helped me not feel miserable while healing from my two wisdom tooth removals. Whenever I had to go to the doctor last year, I would imagine that Ratchet was the doctor I'd be going to see. Now granted, I did make a human form for him, to make it so the poor guy wouldn't have to fit himself into a building much too small for him, it still helped immensely with getting rid of my medical fear.
