<s>[INST] I m a 16 year old female, and I believe I may have Lymphoma. I honestly can t tell if I have swollen lymph nodes, but the middle of my chest sometimes gets a pain in it, making it hard to breathe. I ve lost around 30 lbs in four months, resulting in me being underweight at 98 lbs (Without trying of course, I just don t feel hungry). I have frequent night sweats, my whole body itches, mostly my upper thighs and arms. I get out of breath easily, I just eel so weak and fatigued at all times. I ve tried speaking to my guardian about the possibility but she just tells me its all in my head. Should I speak with my doctor alone Thursday? Or am I just worrying myself over nothing?

The symptoms you are mentioning here are general ones and can be seen with a host of physical problems including simple acidity symptoms and anxiety and obsession. The pain in your chest could be due to acidity and that pain makes you feel anxious, and therefore you lose appetite.
