Fears of being stalked can sometimes indicate beginning of an illness, though sometimes this can be simply a transient response to stress. You should seek help from a common friend or a supportive family member and talk to your husband if possible, but that is a personal decision you have to make seeing your own circumstances. However, as you are going through a difficult time, if your mood becomes consistently low, you find yourself completely preoccupied with this issue and unable to find pleasure in anything, or if you begin fearing that people are talking about you or following you or planning to hurt you in any way, you should consult a mental health specialist as soon as possible. Often these can be signs of depression or a psychotic illness, and can be well managed with a combination of medication and psychotherapy.
