Помогите склонить предложение "Я пошла с мамой за покупками" в 12 временах.

I often go shopping with my mom. I am going to the shop with my mom at the moment.  I have gone shopping with my mom already. I have been shopping with my mom since morning.  I went shopping with my mom yesterday. I was shopping with my mom yesterday at 5 o'clock. I had already gone shopping with my mom. I had been shopping with my mom for 2 hours when you called. I will go shopping with my mom tomorrow.  Tomorrow this time I will be shopping with my mom. I will have gone shopping with my mum by next month.  Next year I and my mom will have been shopping together for 10 years. (В следующем году будет 10 лет как мы с мамой ходим за покупками вместе - нужно добавить слово "вместе", а то звучит коряво)
