Not at all. Imam’s gham and grief doesn’t mean that if it has not been done at a specific place or time then it would not be considered as if you have not done lamentations for him. Rather it has different perspectives. If a person has all the conditions, he must join the gathering and visit the Husainiyya’s and masajids etc. But as you said your conditions did not permit you. Can you imagine our Imam e Masoom that he or they punish or curse someone who has not participated in their mourning gatherings, Not at all.
