Being loved is not a weakness. But a strong requirement to be loved is a weakness because that means you don't have strength to be happy without being loved.
Eating is not a weakness. But a strong requirement to eat is a weakness because you don't have the strength to be happy without eating.
Love is extremely common. It is not particularly much of a weakness because there are plenty of people who will love you. Now, finding that person, or those people, depending on exactly what it means, that could be hard. There are also a lot of people who will abuse your need for love, and so you do have to be careful.
This is actually a sad comment. How did you ever come to believe that wanting to feel loved, which is a fundamental desire (if not "need") for the vast majority of human beings, could ever be construed as a weakness resulting from a lack of "strength"?
And that perspective presumes that being loved isn’t a fundamental human need.
