Anyone wants to be cared for by the others, and also wants to care for others. When you care about the other people around you, you are doing the right thing. You will be loved by everyone because of your good qualities.
However, if you give too much care for everyone, you will unintentionally become a giver. Unintentionally or on purpose, it is easy for the people around you to assume that you are full of energy, full of love.
They assume that you can handle all your problems by yourself, and you can manage your life so well. They think that a person like you will not need any care from others. Because you already have too much of it that you can share with everyone.
But in fact, anyone has a bad day. And anyone needs friends, someone to share and care for.
However, the more you give, the less care you take. The people around you do not care about you although they receive a lot of care from you. You now become a lonely person even when you really need someone to share.
