Are My tremors vit b12 related

Hy Folks

lets make it short and simple my tremors started in January 2024 and then i had blood tests i found out that i have vitamin b12 (165pg/ml )and vitamin d3 (18.8)deficiency and then i went to doctor but he took very lightly and gave like simple medicines for a month and then i somtime i skipped and sometime i didn't take on time .Because i was not aware of how dangerous is Vitamin b12 . Later i went to another doctor but even he just gave me 1 month tablets of like vitamin e and vitb12.

but later after a month or two my symptoms started to get worse like

Balancing problem

Neck Fits

Sense of smell gone

weakness

brain fog

tremrs in legs

tingling

wrinkled palms and fingers

Depression

Anxiety

so then i went to another doctor and he gave me 3 months medicines and even i continued tablets and this time i took it seriously and my others symptoms gone except tremors

so what should i do now please help
