My mum told me she don’t think I can cope :(

So I’m 23 I’m pregnant with my first baby been with my other half for 3 years we live together and are engaged I told my mum the other day I found I was pregnant she didn’t say anything so i went to go see her yesterday she hugs me and says are you sure you want this ? I worry i don’t think you’ll be able to cope she never said that to my two other sisters who have kids....I feel hurt by this and when I think about it just makes me upset any ideas on what to do 😫 she always wrapped me up from a young age as I was premature I was 14 weeks early and because I was that lead to me having learning difficulties nothing major I just struggled to read and spell sometimes and my memory isn’t great but that doesn’t mean I won’t be able to cope with my child
