Loneliness and self-pity really are an illusion. You are as abundant as you want to feel. Trust that you have exactly what you need for today and let the universe increase your abundance.
When alone and feeling blue, look around at what you do have. See what you can donate. See what you can rearrange to make it a centerpiece. Take the time to meditate, give yourself a home spa day---cherish and celebrate your aloneness.
Will you disconnect from comparing today?
