Feeling emotionally sick after eating takeaway

Today was just a long day finished late had to pick kids up from school by the time I get home it’s 5pm I just didn’t feel like cooking so I got McDonald’s and this happens every time I eat junk I feel emotionally sick to my stomach and feel horrible I fed that to my growing baby in my belly :( my friends always try to say hey there are people who take drugs drink and smoke during pregnancy who have healthy babies, but it doesn’t make me feel better :(
