regretful abortion

Am I a bad person for having an abortion when I was just turning 18? I knew I wasn't in a stable environment at the time to raise a child, nor the support from my family and his. ( there are more reasons than just those two.) I think about it everyday and wish I kept that baby. I was so scared and felt so alone. Now that I look back on it I feel so selfish. I have so much anger towards my self I just don't know what to do. Now that I am 20 my boyfriend and I found out we were pregnant exactly 2 years later on the month.  We were ready this time, knowing we were never going to make that same mistake twice. Of course we were both scared but we were going to be ready. We were picking out baby names and talking about how beautiful our little family was going to be. I woke up one morning and I began to spot a little bit. Thinking this was a normal thing in pregnancy. I began to bleed more and began to realize what was actually happening. I rushed to the emergency room and they told me I was having a miscarriage. My boyfriend and I were so devastated. All I could do was blame this on my self. Thinking it was karma for having that abortion 2 years ago. I just don't know what to do. I have no one to talk to about this besides him. I just want other women's support/opinions if you would like to talk to me about this. That was the biggest regret of my life and it will always be.
