Abortion regret

So I got an abortion in January and it’s been really hard on me recently. People around me who know the decision I made, they tell me to just forget about it and move on. Maybe they’re right but idk I just feel this guilt and regret. By now I thought I wouldn’t care. I also feel like I can’t talk about it to anyone because I feel like they will judge or they just say “you wouldn’t be able to care for a child you’re only 20”

Should I see someone like a therapist or will it heal over time?
