I’m going to go with the same advice I just gave over here - it sound like you rushed into summoning with not only zero protections on place, but also with an existing hole in your defenses.
Like him, you should NOT be summoning anything new until you fix this. At this point you have not done anywhere near enough work to learn how to properly protect yourself, actively and passively..
You want to “master your mind” - you best start with a clean baseline where you can know yourself unadulterated by entities.
If this entity is wanted, that’s fine, name it, give it a sigil, and then you can call it back once you know who you are without it. If it cares about you, and a succubus would, then this will not be an issue, it it fights you, manipulates you, tells you you can’t live without it, lies to you to get you to back down from protecting yourself, it’s a parasite and in that case, kill it.
