I am sorry that your mother has passed. It doesn't matter how old you are, the loss of a mum or dad is overwhelming. Look on the Internet what are the stages of grief. It might help you when feelings overwhelm you or when grief comes in heavily. There are no blue prints or time frame for grief or mourning. Each person will experience it in their own way, at their own pace. The five stages of grief (some say there are seven stages) is just a way to try to understand when you swing from one memory or mood to another. If someone tells you it's time to move on, don't listen to them. You are the only one to know when or how to stand up again, and take up your life in a different way. Take your time.
