HELP! ADVICE

Hi so I'm 19 and I just found out I was pregnant Sunday. I'm in cosmetology school and I'm pretty much almost done so baby will be here after I graduate. Well, I told my parents and just about all my family and I just have this one negative aunt that is 23 just talking down to me and basically saying my child will have a shitty life because " I don't have my shit together." Even though , I will be licensed in cosmetology and I will have a job lined up for certain since one of my aunts owns a salon. Everyone else is thrilled. I just want to know what you do about negative comments like this. I've also been with my boyfriend for 5 years.
