thanks everyone
your replies have made me see that its maybe not just the age thing.
i am not "trapped in a life i didnt want to be in" as someone suggested, i am happy to have my kids and fiancee, i wouldn't change them for anything.
but as i said there are certain things i am very dissatisfied with, ie not owning a home (i dont know why i am so obsessed with that but i always have been!!) and i feel i have no purpose in life other than being a mother, which i love but i feel i would get more fulfillment out of life if i did more.
i don't have any hobbies anymore, i used to do pilates and pole dancing classes as well but nowadays when it gets to the evening i just can't be bothered to go as i am so shattered. plus i feel guilty about leaving the kids with my fiancee even though he says he doesn't mind, i think he would because when i have had the (very rare) night out without him he makes "jokey" comments about me dumping the kids on him to go out. plus my son isnt his so that makes me feel bad too.
maybe i am not too old to go back to the singing, maybe its more of a (lack of) confidence thing. the thought of auditioning for a new band terrifies me. i used to be such a confident, sociable, outgoing person but these days i am shy and scared and don't think much of myself to be honest.
i don't know why i have changed so much. 3 years ago i had just split up with my twat of an ex husband after years of unhappiness and had a new lease of life, i was happy, was just about to start my nurse training, i felt sexy, brave and confident and loved my life. it felt like the world was my oyster. i want that carefree, fun girl back.
god i cant believe what a can of worms this has opened.
