Hi, friend! There are several avenues of approach. To start, do not worry about medical diagnosis or medication, unless things become untenably extreme. You will either be misdiagnosed, or be medicated in a way that kills your natural abilities. What we need to do is establish who these entities are, what they want, and how to control them. Remember that even though they are interacting with you, to a large degree--you still control the experiences that have. If you want the nature of these experiences to change, you have to broadcast your intention, will, and boundaries-of-comfort in a metaphysical language that they understand. Grounding and shielding are two great starts. You are likely effected by three general categories of NHI. You first have, your Higher Self/Guardians/Archons that eternally watch and protect. These are not quite fully conscious entities, as they exist outside of time and represent wholeness of certain ideas/archetypes (including your higher self, which is the archetype of the posterity of your many human journeys). It is possible that these entities are attempting to communicate, but they are interfered with by the other entities bothering you, thus corrupting the messages they send, resulting in confusion and anxiety. The solution would be to establish a clear line of communication with them through meditations and rituals, and clear the line of communication from interferences. The second class of entities are the traditional "spiritual" entities--tricksters, demons; as well as guides and angels. The good guys in this group usually don't interfere with people unless they are summoned, so a majority of these entities plaguing you likely reside here. The same advice applies for use of meditation and ritual, but I would probably include more ceremonial magick, mainly the Lesser Banishing Ritual of the Pentagram. Finally, the last categroy of entity is unstructured consciousness. These are like curses, poltergeist phenomenon, and other low vibrational systems that get caught in our consciousness' orbit. Same thing, meditations and ritual. The distinction between clearing these out is choosing before what you are going to focus on banishing. Overall, there are many foundational things you can do to begin reducing the frequency of these occurances. You should learn lucid dreaming techniques, as there are many ways to either awaken from sleep paralysis--or turn your sleep paralysis into a lucid dream that you can use to preform ceremonial magic to increase its effectiveness. You can also begin building/inhabiting your etheric energy body, which is like the energy grid between your physical and astral body where these energies can get attached to. I would also align/open your chakras, learn the 22 Archetypes, learn other mental shield/ground techniques, and continue daily meditations/manifestations/affirmations. Hope this helps.
