18 Dating a man with 2 kids

Gabby
I need some advice I don't know what to do , I'm and dating a man (27) with 2 kids (3,7) and I'm 18 I'll be 19 next month and I suffer with depression and sometimes I feel like this is way to much handle and that I've made a mistake by getting into this relationship I love him but of course I love myself more . My mind is all over the place 😣
