Why do I feel like this?

I literally been crying and crying since I found out I was pregnant and sad about getting an abortion this is my first time pregnant Im22 about to graduate college & Yes I’m a emotional person .. But why am I cry 5x a day just a thought or anything I have been braking down at work and at home crying thinking about everything.. I haven’t scheduled my abortion appointment yet waiting to get my Ultrasound.. I do feel like I’m 100% with my choice but why Do I feel so sad? 🥺 Like I haven’t even did it yet I can only imagine the aftermath.. Any Support Group Pre Abortion ?
