help please!!!

so i am into manifestation for almost 5 years and i've manifested a lot of materialistic things yet but 1 thing that i struggle a lot till date is appearance and i feel like what's the main issue is :

1. consistency
2. visualisation

well i am working on consistency but i need help with visualisation because i really get stressed a lot when it comes to visualising myself in my dream body or like seeing myself in my desired face, i just can't, i always end up seeing myself from 3rd person pov and even though i try to visualize from 1st person pov i suddenly feel very suffocated and my head starts hurting
can anyone help me with this?
i really want to improve
