How do I cope with getting an abortion?

Hi, I just found out yesterday I was pregnant. My boyfriend and I worked together on setting up an appointment and talked somethings out already. We both agreed we cannot keep the baby for financial health and emotional reasons. But everything happened so fast and it really kicked me in a low part of my life. I currently can’t even get on insurance after talking to a couple of people about it. It just feels so sucky because we are so young and agreed even if it was 3 years down the line we probably would keep it. We haven’t talked to anyone about it besides each other and according to the clinic I can’t have anyone even in the room with me when I go next week and I’m so scared. I cry and freak out normally even with simple breast exams. I just don’t know how to feel besides upset even though I know I’d be more upset having the baby.
