How should I feel?

So I had an abortion about a year ago, and a friend of mine also had one a few months before me now she's really depressed and quit her job and is almost suicidal all because of the abortion (she's getting proper help now doctors medication therapy etc.. and she's on the right track) but now I'm starting to feel guilty for not feeling guilty I guess like I feel like I should be more hurt or upset or something? If that makes any sense? I honestly haven't thought about it until recently because of my friend and I feel like maybe I should be upset? Like is something wrong with me for not feeling guilty and regretful? Has anyone else been in this situation? How do you feel about your abortion? Is it normal to not really care or should I be more upset? I'm sorry if this doesn't make much sense just not sure about the way I am feeling or maybe how I should be feeling? I'd like to hear your stories too.
