One of the hardest things in life is the loss of a parent. I have been there with both my parents and both my In-Laws. You really need to stay strong, they are watching over you. My Mom was my best friend, we did everything together, I was lost when she left us. My Mother In Law was the best of the best, we too were best friends. I felt lost, who would answer all the questions I always seem to have? I had to lean on some very strong friends, because when it comes to a lost loved one, I'm weak. It breaks my heart to see pain in my friends eyes. Yes, I support my friends 100%, but they don't see the tears inside me.
Please find a good friend to sit and talk to, or maybe a support group in your town. You must go on with your life. Your Mom still lives in your heart and she always will. Make her proud, she's watching you.
May God Bless You.
