First of all, sorry for any misspelling, English isn't my native language.
I'm 22, I have depression anxiety and panic attacks since I was 13, but now it's worse since I found a lump on the side of my bellybutton about a month ago. I went to the doctor, did a couple of exams like CT scan and abdominal ultrasound, and I found nothing, but I feel pain and have other symptoms and it gets me anxious because I have no idea if my head is creating the symptoms. The only exam left to do Is kinda expensive and now I can't afford it, we have free healthcare here but it can take like 4 months to be able to see a doctor, let alone schedule an exam like that. When I did the last exam, the doctor almost guaranteed that I had nothing to worry about, since something would have already appeared in one the exams, but I still don't know what caused the lump and I still have the other symptoms so I'm freaking out. Anyone gone through something similar? Any advice on how to deal the anxiety? Should I just trust the doctor and try to forget about it?
