You're under alot of stress. The stress of everything you're dealing with is causing your anxiety and depression both of those together can cause everything you're listing.
Especially if they're sever enough.
"Depression may lead to
brain fog symptoms, such as loss of concentration and fatigue. ... If the red blood cells fail to deliver enough oxygen to organs and tissues, a person may experience
mental and physical tiredness, alongside other
symptoms, such as
shortness of breath."

WHAT IS SOMATIZATION?
Somatization is defined as the tendency to experience psychological distress in the form of physical symptoms. Astoundingly, in one
study of 1000 patients presenting over a 3-year period with 567 new complaints of 14 common symptoms (including chest pain, fatigue, dizziness, headache, edema, back pain, shortness of breath,
insomnia, abdominal pain, numbness, impotence, weight loss, cough, and constipation) a physical cause was found only
16% of the time. This doesn't mean that only 16% of all these complaints had a physical cause and the other 84% had a psychosomatic cause; rather, it means that 84% of the symptoms had no
known physical cause. We still don't know what causes migraines, for example, but that doesn't mean we should conclude migraines have only a psychological cause.
On the other hand, another
study suggested that as many as 20% of patients who present to primary care doctors are experiencing physical symptoms that have a purely psychological cause."
