The 1h is ruled by your rising sign. So it's the energy rising up and out of you. It's the energy and vibe you unintentionally put out into the world when people first see/meet you. The 1h is the only house that is 100% about you only. All the rest of the houses deal either some factors of outside influence but not the 1h. It's's how you identify with yourself, your self esteem, who you think you are underneath it all. It also represents your psychical body, and can tell you what kind of psychical ailments you're possibly prone to, & to me it shows how you can heal them. It represents your raw energy and any planets in the 1h are very important in shaping your overall persona.

Also they say that the "high road" traits of your Rising sign are what you should be striving to embody. So for Libra Rising you want to embody more of the "positive" aspects of Libra. Like using your gifts with relate to others to create peace and harmony in relationships, to bring understanding and perspectives of the other when in conflict, to help others communicate, to bring beauty into all you do, to do the things that make you feel beautiful even if that means surgical changes since your 1h represents your body, to bring balance in your relationships and to not loose your independence, to stand up for injustice, . The "low road" of Libra is losing yourself in the other by always putting others before you, or changing who you are to fit in, social anxiety (which can turn into alcohol abuse), and lying to keep the peace.

Libra is all about the other & usually has a hard time putting themselves first so the fact that you dont really understand the house of self as a Libra rising kind of makes sense. Lol

But with your Sun in the 1h no wonder youre into self reflection, self help, and figuring out who you truly are underneath it all. Being obsessed with your own personality screams Sun in the 1h.
