My life sank into the darkness today again. So many stresses i cant handle it!

My girlfriend got pulled over for speeding and she doesnt have her lisence so the car gets impounded at a gas station thats like an hour from where i am. I have no idea how on earth im getting out there with my proof of insurance and my lisence. My sister drops everything to help me and it all gets worked out. So i wait for my girlfriend to get out of work and am thinking,for one of my biggest fears in the world this aint too terrible. She gets out and i go to start the car and all i hear are click click click click. The car will not start. Im freaking out again and after two hours a guy starts walking toward our car. He helps us get it started by jumping it(dunno why that worked since all the interior lights and radio worked when i turned them on to check). Id probably still be at home wondering how i could get out there,if not for my sister. Id still be in the parking lot if not for the guy. The icing on the cake for me today tho is finding out my sister has to go to the doctors tomorrow to be tested for ovary cancer and some other kind cause some of her earlier tests have them worried. I cannot handle anything like this. Why does this stuff happen?
