Crying like a baby when I got my kids from school

So I went to pick up my girls on the last day of school and wasn't planning on getting emotional.  As a matter of fact I just wanted to drop off some paint and foam letters to Kali's teacher and then go.  The main reason I actually went to the school was because I had to pick up Kali's medicine.  She had to have her medicine at school every day and if I didn't pick it up they were going to discard it.  So I went and picked it up.  Then I went to Mrs. Mayfield's room dropped off the paint and such and went to find Kali's class.  Well they were sending off the 6th grade and it was pretty emotional in there.  It was so powerful.  Then I watched Kali give a big hug to her teacher and I lost it.  I had to remove myself from the room for a minute to try and compose myself.  Then I went in and lost it again.  So I went to pick up Anna and her classmates were like why are you crying, which was hard cause I couldn't really talk.  Then her teacher tried to talk to me and I couldn't even get out the words I was trying to say.  I should have gotten a picture of him with Anna but I just forgot.  I couldn't believe I was crying.  It's crazy cause I honestly did not think I would have that hard of a time, but I guess I'm really going to miss that school.  I'm really going to miss my kids teachers, the principle, and the staff at that wonderful school.  It has been such a blessing to be at that school and to have my kids be apart of something so wonderful.  I just have a hard time thinking that that is something that will happen in the next school they go to.  I've even considered home schooling, but we will see.  For now what I know is that I'm grateful for all the things my kids have learned thus far and the people who have helped them on their journey in life thus far!
