Help, ttc

So my boyfriend and I have decided that we want to start ttc. But i am absolutely terrified! I want a little baby so bad. But going through pregnancy and birth absolutely scares me. I don't like being in pain and i have horrible anxiety. I feel like im going to have an anxiety attack while giving birth. My boyfriend is super supportive and i couldn't be more blessed and i want to give him a child, i just can't see past this fear. When i think about being a mom, the first thing that pops into my head is birth. Another thing im worried about is gaining weight while pregnant. Im already very self conscious. I feel like i'll gain too much weight and just absolutely hate how i look and be depressed which will lead to postpartum depression... Someone help me with my fears 😩 ( i didn't mean to post this into this group. It won't let me change it! I'm 24)
