That's deep. Unfortunately you'd disappear because wether or not you survived to finish the consuming, once all the way consumed you would die and decay, blending in with the earth from which you were made and so in essence disappearing. From another angle, science shows there is no such thing as perpetual energy, energy is always lost. So if you only consumed yourself, even if it was possible to fully consume yourself and regenerate, some energy and part of you would be lost so you would eventually be lost to nothingness
