I don't have hardly any friends either. I'm quite shy and reserved and am careful about who I let close to me.
I'm a member of my local church and have two friends I see regularly but with 3 young children, I rarely get any time to myself for socialising.
I would like to go out more and do things but I'm not at all confident even though you think on a first meeting that I was.
I grew up an only child and went through a traumatic, abusive relationship when I was a young adult and so I tend to to back off due to my past which has left me always insecure.
I have a loving DH which makes up for a lot but it isn't easy especially when you live somewhere you haven't grown up and spend most of the day alone looking after children.
The few friends I do have are great and always there for me but I just can't get into the school gate yummy mummy set at my DD's school. Not because I'm snobby, just to shy to get involved. The women who are in these friendship sets all cling together.
I think perhaps that once my kids are older, I will try to join a social group that I'm interested in like a book club and meet friends that way or do a adult education course in a subject I really enjoy.
So you are not alone in feeling lonely!
