I need some opinions and some advice?

So im having an issue with some friends who really aren't listening to me , Im 23 now and my friends keep asking me if i wanna have kids and have a family. Now i have a really bad back round when it comes to drug abuse and eating disorders. So one of my girl friends said something really really freaking stupid that made no sense to me um she said that kids can change you and i do agree but y on earth would you wanna bring a child into this world if your an addict and also have an eating disorder. Im so fascinated as to why she said this and we basically got into it , now i still have an eating disorder and im open about it , i have had this since i was 9 years old because my grandma used to call me fat and would call me names , so ever since then ive battled this for all these years. I was fine about a year and half ago but of course it'll always come back. I feel like if you have mental disorders and drug addictions and all that why would you wanna bring a kid into an unsafe environment. I know for a fact that i am in no way shape or form fit to be a parent and i don't want any kids there just not for me and i wish people would just understand that. Why is there such pressure to have kids i think people in our world think that having kids makes you feel full filled and to me i don't think that at all , i feel like if your at peace with your life and are full filled with your career then you'll be fine. So i guess i'm just trying to understand why my close friends cant except that i have these problems in my life and even with help i cant seem to fully over come them. I know it'll take me years to recover from my eating disorders but i hate gaining weight period it makes me sick and disgusting. I feel awkward asking for advice on this subject since it's a personal matter but no one seems to be understanding me or even listening with there hearts , instead there listening with there heads. So what should i do with this should i separate myself from these people and just leave them alone and find people who truly understand what im going through. Anyone who has gone through something similar could really help me out. By the way im a pre deposed child my mom did drugs while she was pregnant with me and my sisters but did more with me. But i just feel that if i had a kid it would mess me up even more then what i am already and im not on any drugs i haven't been in years but the main thing that does continue is the eating disorders. In conclusion should i stop talking to these people i just feel like there not understanding me with what im trying to tell them.
