trying to enjoy life

Hi all, last February I was diagnosed with multiple myeloma and recently went into remission, my husband has booked flights to go to visit friends in Spain, for the last 28yrs I've been covered for all travel insurance by my husband's employer but now they won't cover me. Could anyone please recommend or know of a company that will cover me to travel. Keep being told to go and do things I want to do and enjoy life again but at the moment obstacles are definitely in the way!. Hopefully someone can help me achieve what I used to take for granted, just going on holiday!! Many thanks in advance. Granny g x
