Give yourself permission to grieve. Feeling sad, angry, let down, or lost is completely natural right now. Pushing these feelings away will only prolong the pain.
Put some distance between yourself and the past. Constantly checking their social media, scrolling through old texts, or looking at photos will only keep you stuck and make it harder to move on.
Look after your physical health. Eat, sleep, get outside, and move your body. Taking care of your physical self is essential for stabilizing your emotional state.
