Weight loss and bowel issues

I’m unsure why my previous post is appearing so reposting.

22F 58kgs

Symptoms from last 5-6 years:

• Unintentional weight loss (I would lose like 3-4 kgs over a period of time and then put back a few after and then cycle repeats)

• Swollen lymph nodes ??? (not sure of this as I felt my neck left side have a lump but ultrasound came out clear)

• Huge stress (due to university exams in the middle and health anxiety)

Recent symptoms:

* Stool is showing signs of some blood (No direct bleeding but more in the stool)

* On/off constipation (pebbles or no stool at all resulting in straining a lot)

* Excessive burping, trapped wind and lower left on/off abdominal pain but not severe

* Difficulty swallowing and sometimes breathing (have been told acid reflux)

* Neuro symptoms (numbness in one side of body then and now, eyes feel flashing light in the dark - mri clear)

* Sedentary lifestyle- haven’t been exercising or walking much recently

* Tiredness

* Some night sweats not every night and don’t need to change shirt level (not sure if it’s anxiety related)

* Low ferritin but high iron serum and low VitD - getting rechecked

* 12 ESR otherwise bloods always coming back normal

* Getting tested for h pylori via sample

I will go to the doctors once my h pylori stuff is done. I’m just really scared that it might be something serious. Ive been told i’m 22 i’ll be fine but reading some posts - it’s not fine.

Any docs or ppl got any advice on these symptoms? Thanks
