Welcome Piper1234:
I'm so sorry for what you are dealing with. It must be hard to have someone you love be so hurtful. It's important for you to take time to care for yourself and manage your stress. Do you have some favorite things to do to relax?
Some information from the quote below might be helpful for you:
1. Check your personal engine light.Think about how you feel when you’re around someone who drains you and upsets you, someone with whom you feel you lose yourself. How does this feel in your body? How does it feel in your mind? How does the presence of this person affect you?
Now look at this list of feelings and sensations you’ve made, and imagine that your body is like a car, with a dashboard full of warning lights. You’ve just identified what I like to call the “check engine light” for your personal boundary system. It’s a security system warning that your personal energy field has been breached, and you’re letting in stuff that isn’t yours.
This is really important. When our boundaries are weak, unguarded, or unclear, we let in all sorts of stuff that isn’t actually our stuff, and we give away our own personal energy unconsciously.
That means you’re dealing with a breach of your energetic security system and a leak of your own personal energy. You’re looking at warning signs indicating that some work needs to be done, some boundaries need to be shored up, and you need to return to center.
2. Ground yourself as preparation for maintaining boundaries.
Grounding is akin to the way a tree sinks her roots to stay secure in a storm. It’s the first tool in creating healthy boundaries—nurturing a connection with ourselves, our centers.
Our root system is both our anchor and our boundary system. It keeps us from being blown about in other people’s winds. It gives us a way to focus and still ourselves to connect with our heart and our intuition. That’s what keeps us steady and connected and focused.
There are as many ways to ground as there are people. I like to take five minutes to actually imagine my root system connecting me into the earth, like a giant oak tree. Here are some other ideas: Meditation; breathing exercises; saying a prayer, affirmation, or mantra in the shower in the morning; mindfulness; chanting or repeating affirmations in your head as you walk.
Try different ways—you’ll find the one that works for you!
3. Notice the people and places that tend to drain you.Before entering those places or exposing yourself to those people, take a few minutes to imagine breathing a bubble of protective energy around you. Think of it as a space that will only allow love and positivity inside it, deflecting anything else. Really see it and really feel the force of it around you. Then recognize what you need to do to maintain that space.
These three steps will help you create and maintain healthy boundaries. Building boundaries is like any muscle or practice—the more you work with it, the better it serves you!
