Hi durga,
I understand how you feel because it wasn't easy for my mother when I got sick, it was, in her own words, a "heartbreak."
As you could understand, a lot of woman want to have children.
As someone with SZ, a woman has to weigh carefully this decision, especially if it means she will have to go without medication during the pregnancy.
If she continues to take her medication every day as prescribed, it's possible she will recover to the best of her ability.
Your question, "Will she ever become 'normal' after two relapses" I want to address now. From your question, I take it she is having symptoms or acting weird in her behaviors. Recovery from SZ, and from an episode, isn't quick. It takes time.
Please, refrain from thinking in terms of a deadline for her recovery.
I urge you to mourn the past, open your eyes to the future, and always keep the hope that your sister can recover. Recovery means different things to different people. At this point in time, your sister may need to do what it takes to keep her head above water, before she can start doing other things.
I recommend you read my SharePost here, "Resilience: A Key Recovery Skill" that is featured on the homepage of the Connection. Not everything will possibly apply, however, some of it will be useful as your sister begins to heal from the latest episode.
In time, your sister can recover.
I suggest you join a NAMI [National Alliance on Mental Illness] family support group.
Call their national hotline at (800) 950-NAMI (6264) to find the phone number and location of a local affiliate in your area that hosts a support group for family members.
You could also write SharePosts here at the Connection, and we will support you with encouragement for what you are going through. Click on the blue "Connect" menu, and click on "Create a SharePost."
We are a welcoming Community that is going strong.
Best wishes,
Christina
