Single (Again?!) and Yet Unavailable

Yes. I am single again but then, I am unavailable. My heart has been hardened by past experiences. I hope in time, I'd be able to accept someone in it again. As of now, I have to love myself first. Sometimes, I feel the urge to ask my Maker for signs, whether I am meant for someone or for single blessedness. But I heard somewhere that I should not be worried, that I should just lift up my burden to Him because His will be done. Well then, His will be done, be it single blessedness or not.
