I have recently stepped into a new career, one that has taken doing a PhD, working my arse off and generally changing a lot. I love it on a day to day basis, I am fulfilled, happy, interested and think what I am doing is really worthwhile. Our income is higher, we can afford a decent standard of living for our children and are generally a very, very happy family. The career itself is going very well and is proving very promising in so much that I am being recommended for promotions which I didn't expect to even look at for another year or two, so all looks good. I have been doing this for over a year now and still love it completely, however when I started I was excused from the trips away and conferences as my son was only 4 months old and ebf. A year later and it is clear I have to now participate in this part. I HATE being away. In the day I am engaged and happy and enjoy what I am doing but at night I am so lonely and miss my husband and children so, so much!! We rely on my income as my husband does most of the childcare. It is likely I will be away now 4-6 days out of every month or two. Have I made a mistake in changing careers?
