While your friends might want your help today, you should make sure you are taking time for yourself.
Your friends and those around you may have some issues to deal with today and they may expect or ask you to help and support them. While you would normally be right to help your friends when they need you, make sure you are not doing this at your own expense today. It's the right day for you to be relaxing and taking some time for yourself, so do not feel pressured into doing things for others.
