"Śūnyatā ["Nothingness"] signifies that everything one encounters in life is empty of absolute identity, permanence, or an in-dwelling 'self'. This is because everything is inter-related and mutually dependent - never wholly self-sufficient or independent. All things are in a state of constant flux where energy and information are forever flowing throughout the natural world giving rise to and themselves undergoing major transformations with the passage of time.
"This teaching does not connote nihilism. In the English language the word "emptiness" suggests the absence of spiritual meaning or a personal feeling of alienation, but in Buddhism the realization of the emptiness of phenomena, at basic level, enables one to realise that the things which ultimately have no independent substance cannot be subject to any irreconcilable conflicts or antagonisms. Ultimately, true realisation of the doctrine can bring liberation from the limitations of form in the cycle of uncontrolled rebirth." Source:

The idea behind emptiness isn't to feel nothing. That's really off. The aim is to see the everything is interdependent and fleeting, changing, including the contents of your experience, as well as the things you try to make permanent (money, relationships, status). Understanding this helps you shake your fixations and fears, since you're no longer trying to make your SELF permanent. Since desire (thirst) is the ultimate cause of suffering, and the illusion of self is the ultimate cause of desire, insight into the empty nature of self (empty of an inherent, solid identity called "me" or "I") relinquishes desire and suffering and opens the door to peace, interconnection, and love.
Moreover, many Buddhists (especially those from a Vipassana tradition) practice meditations on
metta which translates to kindness or universal/fraternal love. Quite the opposite from trying to feel nothing, wouldn't you say?
