When to see a professional for PPD

I thought I was doing SO well. But lately my bad days are outweighing my good and I think a lot of my current situation is weighing so extremely heavy on my shoulders and reallystarting to effect me. I'm exhibiting all symptoms of ppd, but my son is 8 months so is it still ppd? (Probably a dumb question but FTM so whatever. 🤷🏼‍♀️) Anyhoo, when and where should I reach out for help with this? I feel myself withdrawing from people and things that I love. Getting upset way easier. My main thing that terrifies me and makes me so so so sad is I have been unable to sleep leading to such deep exhaustion that I dread every single day. I am not able to be the mother I want to be for my son, to be playful and to go out places. Some days I HAVE to set my son in his jumper and take a cold shower because I am so tired I feel I could literally collapse with him in my arms. I forget about things I do in the night like I'll wake up with my son in bed with me and not remember bringing him into bed to nurse him, I feel extremely hopeless and trapped due to being jobless and just STUCK, that's a whole different story but I made a lot of sacrifices to be closer to immediate family and it's kicking my ass and putting me in a hole. Mentally and financially. I had to stop school because they messed my leave of absence up right after I had my son and I have to pay 2 classes out of pocket which I can't afford. I'm a single mom and I really have no other option right now since I did go this route I've exhausted all of my resources in the process of being stubborn about no help. I've tried everything, vitamins, essential oils, yoga, etc. nothing is really helping I just feel it getting worse.

Stuck. Tired. Confused. Helpless. Incompetent. Ugh.

Who has experience with this?
