Is it ok to feel sad?

Ok so I am pregnant at 25 weeks 3 days today. This is the furthest I have carried a child. We have buried two babies and had two early miscarriages. So this baby is such a miracle and blessing. I live in Texas and my only family member by blood is a sister. We hardly ever talk. I will message her and ask her how things are and what not but she never replies so I just stopped trying. The rest of my family is in California. So I have my husband’s mother (she lives 4 hours away) and his grandmother (45 minutes away), we aren’t super close. Anyway, I’ve never been to a baby shower or know exactly how it works. Not sure if I’m supposed to throw it for myself or not. I thought a family member hosted it for the parents to be. No one has showed any interest in doing it or offering to help me in anyway. I don’t mind doing things on my own I’m used to it. It just makes me feel sad, not for me but for my son. I see this baby as a miracle but no one on his side of the family or my ONLY sister in this state who lives only (20 minutes away) has offered any assistance. I work 40+ hours a week and see a doctor every week as I am high risk. I see my regular OB my MFM and next week I see a fetal cardiologist to check my baby’s heart. I just wish I had someone who, I don’t know cares a little bit to offer some help. I’m not even asking for money just help getting things together. Maybe I’m being selfish but my husband works out of state and is gone for a minimum of 21 days but this hitch he is gone for 52 days and it adds so much stress. I told my husband maybe we should just cancel the baby shower because it’s a month and a half away and I have nothing ready. I bought a few things but with everything I’m so tired and stressed and my depression mixed with my hormones has me all over the place. Not sure what to do maybe I’m just being too emotional and sensitive. Sorry this is so long I just have no one I ask about this. So my question is should I continue to plan this shower alone or should I just cancel it?
