be ok with being alone

I’m used to being with someone who loves me and takes care of me. And I’m used to taking care of someone – it’s like my worth as a person depends on how much I love, care for and give my all to someone else. I’ve just recently realized that I shouldn’t measure myself that way, that I should be happy first with myself, before I can truly be happy with someone else. Having someone to be with is nice, but it shouldn’t be the end-all. It should just be the icing on the cake. But even without the icing, the cake should still be good.
