Geology Student Seeking Marine Internship: What Topics to Focus On?

I am 31 years old and have been married for 6 years. My relatives keep pressuring me and scaring me, saying that I haven’t had a child yet and that I should have one now. However, we are not financially prepared at the moment. We have just bought a house, and the loans have recently started, which exhausted all our savings for the down payment. My husband’s family had a very weak financial background. They had nothing, and he struggled a lot, even living in someone else’s house to complete his education. Only he knows how hard it was. Now, his salary has improved, and I am also employed. Additionally, we are entirely responsible for my in-laws, as my husband’s elder brother neither got married nor provides any support for the parents. We are under a lot of pressure right now, but everyone just keeps asking us when we are going to have a child. I’ve seen how my husband struggled with limited finances when the family was financially weak, and I don’t want to show such hardships to our children. On top of that, I am overweight and focused on losing weight to ensure I can be healthy. I feel very stressed and confused, but my husband is fully supportive of me.
