What to do next

I was working as head of data science and analytics for a small startup , today the role was made redundant and i told to go . I would be getting few months of salary . I am 45+ i dont know what to do , i applied for jobs in conglomerate like walmart , tesco aa director data science but could not clear rounds . I applied to many companies as director without any success . I think my career is over , i dont know what to do entire day , its very very depressing . I will not get a next job
