Whenever we are in a place in our lives where we are starting to open up to feelings we have not been feeling, we may get a bit swamped if we don't have methods for handling those emotions. In order to open up to good feelings, we must open up to all feelings and do the hard work of processing the backlog most of us carry around. Energy psychology offers some powerful ways to processing emotional energy in a healthy way. My own approach combines energy psychology techniques with centering, grounding and inner guidance work. There are many practices that can assist you. What are some of the ways you have already been successful in working with your emotions and energy? Do you know some ways of clearing your own energy field, centering and grounding yourself? These are very important. Sounds like you have some deep grieving to do to heal your heart. If you know and do Reiki, and even if you don't, I would suggest putting your hands on your heart and taking some deep breaths with deep sighs as you allow the feelings to surface and clear. Play some gentle and nourishing music. Get hugs from your friends.
I'm planning on creating a database of energy interventions to put on my website to assist people in their own energy self-care. In the meantime, you might want to check out some of the energy medicine and energy psychology recommended resources (books and websites) that are listed on my website: www.aligningenergies.com. A good resource for starters is Donna Eden's Energy Medicine book. Her 5-minute routine should help a great deal. Other techniques in the book might also offer some assistance. The Celtic Weave is especially effective for strengthening your energy field for healthy boundaries. Expelling the Venom is a great way to help yourself clear anger.
Dreams are another topic. Are yours just strange, or perhaps actual nightmares? Do certain themes repeat themselves in your dreams? Have you done any work in exploring archetypes? Dreamwork is an extremely rich doorway for accessing deep personal and spiritual growth.

Vera, emotions are energy. Our repressed emotions are stuck energy. They stay stuck because we resist feeling them. The very best way to resolve these negative feelings is to just FEEL them fully and ACCEPT them without Condition. Embrace them until they subside or resolve into peace.
