PPD or general anxiety/depression

My son is almost two this year and I'm severely depressed about the stage of life I am in. I feel guilty not being able to have the perfect life and enjoy my son and give him all the attention he needs. I am a career woman mandatory teleworking, the bread winner of the house, the one who manages all the bills and money, the SAHM, along with taking care of all house stuff such as cleaning, cooking, etc. I want another baby in the future but if I cannot relax or rest it will be impossible for me. My husband works 14 hours a day 6 days a week. On Sundays his only day off he is gone for 4 hours purchasing work material for the new week. There is no way communicating with him about how I feel because he'll help a little and then its the same cycle. I feel like I'm going to collapse. Within 3 months my son has been having fevers for unknown reasons. I have anxiety because I think of the worst but I hope its just his teeth. I've been taking him to the doctor and he tests negative for most common viruses.

I feel that my PPD or just general depression gets worse when my baby is sick because it hurts me to see him uncomfortable and in pain, there isn't much I can do for him. I give him tylenol for comfort and give into TV time mostly Cocomelon. Then I have to worry about my career, the bills, the house, cooking, cleaning, and laundry. How can I make my life easier? I feel like I'm going to collapse one day on the floor. When my baby is sick I'm lucky if I take a shower or eat a meal. All I do is Google stuff and can never figure out whats wrong with my baby. The doctors aren't much help either.
