Mom Of 2 At 21?

My Daughter was born May 11 2018 (she wasn't planned, I was on Depo shot) then shortly after I got pregnant again because her dad 'wanted' a big family, now I am Due April 2019 & their dad broke up with me because he doesn't want a girlfriend, all too easy for him to do, so now I am 20 with an almost 6 month old & 5 months pregnant, wilk be 21 on February...I Need Advice someone to talk to about my situation, it's a very long story & I really need to talk to someone that will be honest but won't judge. Thank you!
