Yesterdays situation has not improved today and you still feel like you are being taken advantage of. Gently tell others that you can only deal with so much and take some time out.
Today you continue to feel as if you everyone around you wants a piece of you. It's great to be needed, but you are struggling to keep up with the demands those close to you are putting on you. Both at work and at home you are going to feel the attention is a little too much. You only have one pair of hands and you can only be in one place at a time, so gently tell others that you are doing your best, but you need some space. Put off anything that can wait and take some deep breaths.
