To the question in the title of the thread:

NO, you are not being needy.

need·y (nd)
adj. need·i·er, need·i·est
1. Being in need; impoverished. See Synonyms at poor.
2. Wanting or needing affection, attention, or reassurance, especially to an excessive degree.

You do not want anything to an excessive degree, so you do not qualify for the "needy" label. I disagree with the dictionary, that says: "especially to an excessive degree". The way this word is used in practice (and it is used widely), it ONLY refers to wanting excessive affection/reassurance/attention.

You do not want anything in excess. A few words of affection are not excessive. So no, you are NOT NEEDY. But please table wanting those few words of affection for right now, in order to save yourself more disappointment.
