sending you a warm welcome.I used to think I was strong too,but losing my husband completely threw me,I think partly it is them that gave us strength and without them,literally the wind beneath our wings we come crashing down.
It is a long bumpy road ahead but gradually you will find some of that strength again.
But I am a lot further along this grief journey now,and although I am note quite as strong or quite as confident as i used to be that resilience is still there,not soaring but catching the odd thermal.
