Generally speaking, if you are experiencing that type of a reaction, then as mentioned, you need to start looking into it, and soon.
Angels exist, but the degree in which they exist depends upon your belief system. Every culture, and every religious practice, has "angels", though they may not always be called that. Angels are simply spiritual beings who exist on a higher plane of energy than we do. Depending on your preferred practices, you could start with enochian magick, or you could focus on the more "psi" related aspects. For myself, as a Reiki practitioner, I often deal with angelic forces. As beings of white light, they are very useful in healing both physically and spiritually. As a ghost hunter, I also use their energies when cleansing a home.
If you practice Magick in any form, my recommendation is to pick up a spirit board (not a ouija board), and bless and protect the board. When using, specify that you wish to make contact with angels, and ask that any who are willing to speak to you come forward. You can ask them any questions you see fit. If you decide to do so, post your questions and the results here, as I would be curious to know which angel contacts you. I usually talk with Gabriel or Michael. I have spoken to Raphael and Tsadkiel as well, though only because I called upon them specifically.
Enochian magick is also a great starting point for those wishing to use Angelic forces in magick practice. There are many types, depending on which material you use, but my preferred is Enochian sigil magick. It works, in theory, very similar to Goetia practices. You learn the sigil for an angel, and what that angels strengths are. You create a talisman with that sigil, and use it directly in practices, or simply keep it on your person to see how it changes your day-to-day life. There are other practices in Enochian magick as well, including evocation and invocation, although I know far less about that.
If you wish to practice from the perspective of psi, you could easily start with a meditation focused on making contact with your guardian angel. As with spirit guides, we all have particular angels who watch over us in our physical lives. Mine is Michael. Then, you could go so far as to attempt to contact them during an OBE/astral journey. Understand, however, that angels are…picky. They have their own agenda, and often times they will leave a conversation halfway through just to go do whatever it is they want or need to do. Be prepared to have a lot of conversations ended before you are ready to end them.
