After an appointment in Windsor (we are Leamington resident) with my 6 yr old son this morning we decided to head across the city for some lunch at one of his favourite restaurants. We didn't make that lunch. While stopped at a red light at Tecumseh Rd. east and Jefferson I had a medical emergency happen to myself. I am normally a healthy person and this situation happened suddenly I knew I had to get off the road and find someone to help me with my son because I knew something was not right and felt as if I was going to pass out. I managed to pull my van into then closest driveway I could safely get to which was a small plaza. I told my son something was wrong and mommy needed help and told him we needed to go into a store for help. He quickly got himself out of his car seat and helped me into Sofia's bridal where I seen a staff person right away. My son yells out my mommy needs help and I asked them to call 911 as I felt like I was going to pass out. The ladies in the shop quickly came to my aid and helped calm my son. They called 911 and kept talking to me and had me explain what happened which was extremely frightening to myself and my son. As the staff at the store I believe their names were Janet or Janna and Barb and there was possibly another staff I'm sorry if I have your names wrong and then there was a young girl that was a customer in the store that sat with my son and talk to him and offered to stay with my son until a family member could make it to the city from Leamington. My son however did come with me in the ambulance. The paramedics arrived and the staff and this young girl at Sofia's bridal all stayed with me and helped calm my son the entire time and I can't thank them enough and I am sorry that I did not get the name of the young girl. Also the paramedics were also wonderful to both my son and myself. Thank you all so much and you have been spotted for your very compassionate hearts. You all made what could of been a very truamatic experience for a little boy much easier. Thank you from the bottom of my heart. We are now home after having tests done and follow up appointments set so that answer can be found to whatever caused this.
