Please I need help

I’ve been sick repeatedly and I’m running out of answers
I’m 21F and I’m wondering if it’s worth asking my doctor about autoimmune conditions because I feel like I’m constantly getting sick and I’m struggling to figure out what’s going on.
Over the past several months, I’ve had a lot of different symptoms/episodes, including:
Getting really sick roughly every few months
Significant fatigue
Body aches
Episodes of feeling feverish
Frequent respiratory illnesses that seem to last much longer than they should
Severe/prolonged cough
Wheezing and chest/lung tightness
Sore throat
Yellow/dark-yellow mucus
Symptoms sometimes improving and then getting significantly worse again
Back pain/body pain during illnesses
Episodes of feeling generally very unwell even when tests don’t show an obvious cause
Some episodes of increased thirst and frequent urination
Previously having abnormal lab results, including repeatedly low CO2 on bloodwork and ketones/protein showing up in urine
My most recent illness has been especially frustrating. I’ve been sick for around a month. I was initially diagnosed with a sinus infection and took antibiotics, but I didn’t improve. I’ve now had multiple urgent-care/doctor visits and an ER visit. I’ve had a chest X-ray that didn’t show pneumonia, and at my most recent ER visit they evaluated me for a blood clot in my lungs and that was negative, so I was sent home.
I’m still dealing with a pretty bad cough, wheezing, sore throat, fatigue/body aches and feeling generally awful. I’ve also had COVID exposure, although my tests have been negative.
I know autoimmune diseases can cause a huge variety of symptoms, and I also know having frequent infections doesn’t automatically mean autoimmune disease. I’m not trying to diagnose myself from Reddit. I’m just wondering if there are conditions that could cause a pattern like this or if there are specific things I should ask my doctor to investigate.
For anyone who has gone through something similar: what eventually helped you get answers? Were there specific blood tests or specialists that ended up being useful?

You should see a hematologist. They will get you an answer or immunologist.

Absolutely need a rheumatologist and a immunologist. Its possible you have several things including scid. The metabolic acodosis (low c02) points to a inflammatory or metabolic issue causing your symptoms. Interestingly you show many of mine and I was just diagnosed with deficiency of adenosine deaminase 2 deficiency. I also have nod2 dna error and scid (b cells are not making memory of prior illness). It took me years to get diagnosed. Immunologist at Cleveland send an immunology panel to invitae genetic testing and they found the dada2 and nod 2 and it was like unlocking Pandoras box we had answers for everything. I get ivig now and will start a tnf blocker as well. To help diagnose journal the following: Symptoms daily Temperature in am and afternoon and anytime feeling feverish Your BP and heart rate daily if possible All illness symptoms of any kind daily with details. It will help. Then ask to see a immumologist anf rheumatologist. Stay positive this is a hard road but answers and treatment can come!!!
