Thank you for contacting JustAnswer.
I am sorry to hear about the problems you are experiencing with your mother. It can definitely be a stressor to care for an elderly parent. It is important to remember that there is no reason for you to judge your feelings, only your actions. Your feelings of resentment or guilt are telling you that this is an unhealthy situation for you. It is important for you to listen to these feelings and consider whether there are any options for you to set some limits for yourself. For instance, can you get any help, even if it is very part time, from family or friends? In addition, you may want to explore whether there are any limits you can set for your mother, depending of course on her medical condition, regarding allowing time and space for you. Are there any options of nursing care or other support that your mother may be eligible for?

You may want to vent some of your frustration through letter writing, in which you write letters to your mother or others that you may be upset with and then shred them without sending them. This helps to release your feelings in a safe way that doesn't harm anyone. It is important for you to remember to take care of yourself while you are taking care of your mother. Finding time, even if it is brief, to do something for you is vitally important. If you don't take care of you, then you will burn out and not have anything left for your mother or yourself. Exercise, meditation, eating healthy, spending time with supportive people and being patient with yourself are all important. I hope this answer is helpful. Please let me know if I can clarify further.
