Hi there, welcome to SoM.
Although mental conditions could effect spell outcome, the spells you are trying will never work because it isn't possible to transform physically into anything. I would recommend looking into astral projection as many people believe transformation in the astral to exist.
To post a spell you need to be in a council position of a coven, the Spell Casters coven has an automatic promotion to Council member but it is usually recommended to ensure the spell is real and can work to reduce the number of false spells on the site.
I hope you enjoy your time here, it is a nice community.
