Almost impossible to answer in a few words. So many levels. Looking back, I realise that being female in my formative years was a huge obstacle, but I just kept on battering away - now I see how that was one of a number of actions which has led to the powerhouse we have today.
Obstacles - being of an artistic/historical bent in a scientific age. All husband's friends were scientists and very 'nice' to me. 'Specifically' is personal and involves divorce after the realisation that an assumed happiness and long-term relationship (30 years) was deadening and going nowhere. This led to the appalled realisation that I went under or 'jumped ship' - very frightening.
In the end, I did not want to be subsumed so I summoned all my courage, threw caution, children (then aged 18 and 21, so not so bad)and security to the winds and went on my apprehensively merry way to France and a total change of life and society.
There is no other way to say this - it was hard. You could lose yourself in bucolic pleasure and timespans, but not all the time. I found a society in which I could function and find friends - lots of them, but only 4 are brought back to UK with me. I did it by going out and helping people, finding a place where I was needed to help other ex-pats., giving lessons for nothing to help people communicate in French so they could manage in their lives. They became friends and a support group.
So I overcame obstacles by simply plugging away, putting one foot in front of another and meeting and being friendly to people. I was hugely lucky in meeting Mr. J2, who was also similarly adrift and coping. Now we are together, married and living in a village in E. Yorkshire - but we have both been through massive upheavals and obstacles (his was being widowed whilst in France). Life will always bring obstacles; you get on with it.
