Merry meet @Kristin7 
Welcome to the forum- thanks for sharing your question! I agree with @Amethyst, meditation is a great way to help you increase grounding, enhance your focus, and get in touch with your inner self 
If you have an interest in Chakra Work, I also recommend working with your Third Eye Chakra- a way to improve your intuition and spiritual prowess. You might use a Third Eye Crystal Grid or this Third Eye Meditation (from a past group ritual. A shared ritual with a new theme is hosted every week in the Sacred Space Category of the forum- you are warmly invited to join!)
And if there is ever a time when you can feel a presence but can’t directly communicate with it, it may not be because your powers have weakened, but rather that the entity or spirit itself is too weak or distant to communicate. In such cases, you might turn to divination. Divination methods can work as tools of communication- from Oujia boards to tarot to pendulums- divination is a great way to reach out to forces beyond the physical realm 
Wishing you good luck, Kristin! If you have any other questions (or just want to chat with like-minded magick lovers) feel free to reach out in the forum- you have many friendly coven members happy to chat
Blessed be!
