Hi... You are going through a big change in your life and it is okay to feel this way. Maternity changes a person's mind differently. Some people experience little change and some experience big changes in their lives, relationships, personal & social image, emotional & perceptual field, etc.
You can seek Counselling for your concerns. It will help you vent out your pent up emotions and will provide you a safe and secure place to work out your measures to deal with this situation more effectively.
We cannot change how others behave but we can change our own perception & behaviours in such a way that other people's negativity stops effecting us disproportionately.
Next Steps
Consult a Psychologist.
CBT along with Interpersonal Guidance and Counselling is required.
