I am so sorry for the loss of your father. It is never easy to lose a parent.

The posters have given you really great advice and I am going to second what they have posted. For now, please listen to what they have said. You need to take this time for you. You have had two major losses in the last year. The loss of "K" is still weighing heavily on your mind and soul and then your father passing just recently. Now, you have twice the amount of weight on your shoulders at this time.

Step away for a bit, give yourself time to grieve and find your footing once again. You cannot help others until you are healed. It's the old saying with the oxygen mask, you have to use it first and then use it on your children, etc. For what it is worth...you definitely need some time for yourself. Can you get away for a few days and just relax a bit?

As for your step mother, she needs the time to grieve as well. Give her the time and space she needs and she knows that she can reach out to you if she needs to.

Time to focus on you, my friend.
