Tired

I just got home. I told my boss today that I will be leaving in April. They may hold me to my contract. I don't know what I'll do if they do. Like most teachers I work evenings and weekends. Everyplace I went with my husband I had my laptop in my lap or a stack of paper with me. Now I don't care, I like my kids but I am really tired and feel so stressed, always trying to handle all the paper work of J's death, school work all day long, mowing season coming, a memorial to plan, sick 90+ year old father in law. I haven't even been able to find anyone reliable to let the dogs out during the day. The lady I was paying to do it was not doing it. Now I know those of you with young children have it a lot harder than I do. But I needed to vent. What do you think about leaving work before the school year is up?
