Aborted my baby because of prenatal hormones

When I found out I was pregnant I felt very mentally ill like I felt very confused and not myself for weeks. During this time my boyfriend suggested me having an abortion and at first I said I’m keeping the baby but then because I felt very off, I agreed to abort. As soon as I aborted, I IMMEDIATELY felt back to my normal self/ mentally sane. But then came this insane amount of regret and realization of what I’ve done and I’ve been suffering It since I aborted. Now I’m scared to ever get pregnant again because I’m scared I’ll feel mentally insane again. Does anyone know anything about this..? Or has felt this way before??
