Is it normal to feel guilty?

I'm currently living in Watford Herts with my mum and dad. I also live quite close to my grandparents, sister and other extended family. I've been dating my boyfriend for nearly 3 years now and it's a long distance relationship as he lives in Newcastle. From the start it's akwTs been said that in the future I will be the one who eventually moves up to him. Now that time has come and even though I am excited to move in with him, I can't help feel worried and feel guilty about moving away from my family. I know it's not the other side of the works but still it's quite far from just being around the corner. My parents have always known that I would eventually move up but I just help feeling guilty and like I'm abandoning them. I am extremely close to my 2 year old neice and would miss seeing her everyday. Also my sister is due again soon and I feel bad about missing the new baby as it grows up, coz I have been their with my neice throughout everything. But obviously can't do this with the new baby when I'm 200 odd miles away. Am I being stupid or is this normal to feel like this? I'm 30 next year and want to have my own little life and family one day. Has anyone been in this situation before? Any advice would help. Thanks.
