Feeling empty

I'm not sure if this in the right place .. But here
I go... I'm getting married in about a year
And I'm feeling completely empty in regards
To family.. My mother is an alcoholic, my father
Has a brain injury and my siblings are not
Exactly a family unit.. I guess I've always dealt
With the fact of not having active parents
But as I get older and closer to starting my own
Family it seems to hurt more.. I get extremely
Jealous of friends with their family units and
Just wish for once I could feel that .. To make
It worse my fiancé mum is another alcoholic and
His dad isn't one the scene.. I guess I always hoped
I'd marry into a family that loved me and I feel let
Down again... I love my partner to bits but it's gets
Very hard for him as I sometimes am on an emotional
Roller coaster... Any ideas how I can expect this?
Or will this always rears head in my life.. ( I tend
To melt down every so often)

It sounds as if you have so many things going on, and so many concerns that you hardly have enough energy left for YOU. Who is there to listen to you, and to offer you emotional support? Is there anyone you could talk to? Would you consider therapy?
