A thought went trough my mind reading what you wrote.
I think sometimes a mother or a father doesn´t realy have the strength to face things as they are. As a mother you want to fix it, give a tablett or comfort and it´ll go over. Sometime it´s easy because if you can´t fix it yourself you can always take your "child" to the doctor and tell him to fix it- then you have done someting wich feels the same as if you fixed it. And I think that´s were the problem lies, as a parent you need to fix things for your children. And when you can´t you either get frustrated and sometime even angry. Or you can go in denial just because you can´t handle the thought of your child suffering, it becomes some kind of psycologic defens´- you minimize the problem instead.
A wise person once told me that one of the hardest things in life is realising that your parents also is just ordinary people with the inadequacies ordinary people sometimes have.
I truly belive that your mother loves you and would do anything for you but this time she didn´t have an answer for you but insted of facing that ( wich could be rather painful for her ) she just said the first thing that came to her mind- she tried to "fix it".
By the way. There are two acupressur points on you stomach. put your fingers around about
2,5-3cm straight out to the sides of your bellybutton, there you push down right in and hold for 10seconds and then let go. It´s belived to get your intestins to start moving letting your gases out.
Everyone of us get´s upset once in a while and venting sometimes makes it easier to handle.
Take care!
