You must have unconditional love from at least one being.

Someone who loves you for who you are, not to change you into something else. Not someone who is blind to your faults, but someone who truly loves the real you, who truly likes you.

Someone who would never abandon you only because you got sick, or you lost your money, or you lost your looks,  or because the honeymoon is over, or because a better deal comes along, or because your usefulness to them is over. Someone who truly cares what happens to you, will nurture you and do all they can to help you in life.

If you also feel unconditional love and commitment to that person, than something miraculous will happen. True and ever-increasing love will be exchanged back and forth getting stronger and more powerful all the time into eternity. And "the gates of hell shall not prevail against it."

No matter how flawed you are, remember that the world is full of flawed people. All are flawed. If you haven't found unconditional love yet, it is just bad luck, and a matter of time, if you keep trying.

If you die before you find it, I add my testimony to the millions and generations in different cultures who say that there is a higher power that does love you unconditionally. The love of the higher power is the only love that is truly completely perfect and truly completely eternal. It is far more than any trivial human love. So love yourself, because as a creation of a higher power, you deserve it. And remember that the higher power loves you unconditionally. In time you will know this for certain.
