I just don't know where else this topic would fit so I'm posting it here...
I'm hoping you can give me a bit of perspective (but please don't flame me):
I'm 20 and still doing my degree
in a long distance relationship which will stay pretty much the same for next 4 years because of study (so it's not like any of this is in the cards for a while)
And yet I am constantly thinking about having kids and starting my own family. (Heck, I'm a member of mumsnet...) It feels like my degree and current life are just time-fillers until I get to an age where starting a family is seen as acceptable. Part of why I'm posting this is that it's crippling uncomfortable talking about this with anyone - friends, family, boyfriend - they worry I'll do something silly or they think it's a bit wierd and tell me so. I guess it feels like an obsession. 
I know it's not helping me and I'm 'wishing away my youth' and it probably stems from a lack of a fulfilling relationship with my Mum, but the fact is I have these strong feelings and thoughts. And I know that I need to spend the next few years developing myself as a person - but I feel a huge daily frustration because it's like keeping a big secret and I wonder how I'll cope with this fixation until then.
Gosh, this has become a bit long.
I just want a bit of perspective - I feel all out of sorts and don't have anyone to talk openly about this with.
