I was never quite the believer in vampirees, but when i was 7 years old i saw an angel standing in my doorway, i was speechless, i knew something was up with me, when as soon as the angel rose thru my doorway and vanished i was able to run downstairs crying telling my mother what i saw. But in the past 3 years or so ive felt an emptyness or darkness within me, i dont feel really any emotions and i was raised in a good home (thankfully) but i feel like im a vampire within. Please can anyone hep me with fully becoming one. Ive tried everywhere.
Physical shapeshifting is impossible, sorry. Alternatively, you could look into spiritual vampirism, as there are paths that practice that, and you could practice astral shifting. There are also otherkin communities that accept identifying as a vampire (you'd still be physically human, though).
Also, there are snap on fangs that you can alter to fit your mouth. I have a pair I got for about $20. As long as you clean them regularly and don't eat or drink with them in they can last for quite a long time.
As a side note, if you're chronically feeling empty and emotionless, you should seek psychological help. That's not something that can be remedied entirely by magick.
An astral shift is a practice of consciously (and temporarily) changing the image and energy of your mental/spiritual self while in a state of astral projection/travel. It does not change you physically but for some it can be a method of spiritual exploration.
As far as being vampiric, the best community to look into would be sanguinarius.org. It is one of the longest running communities catered specifically to vampirics, and is full of information. There are also a couple of articles written on the subject on the site here, both for and against the idea. I reccommend reading both sides of things to best educate yourself on the facts and foibles.
A while ago I popped up one such article to save on having to type a novel every time the topic came up. If you want you can give it a read;
