If someone is cheating you, or treating you unfairly, you might need to withdraw and let time heal your heart.
Pressure from the outside world could be causing you to feel deflated or stressed. You are particularly sensitive at this time, and even your own negative emotions could trigger deeper feelings of sadness that cause you to think too critically about yourself and others. You have some important decisions to make, and some important work to do, but you can only make things happen if you take control of your emotions and filter out all of the unnecessary negativity and confusion. Trust you intuition, seek advice, and you'll be able to move mountains once again.
If your job requires you to sit for most of the day, get up and move around. It's an important way to improve your mental and physical health.
