Health concern

I’ve been to many Drs: GDs, MDs, Cardiologists, Endocrinologists, Immunologists, Neurologists. At some point it just felt like each Dr is throwing the ball (me) at the other departments’ court 😂

Done lots of blood work, some came out slightly high/low, but nothing major.

Recently I’ve been having bouts of intense tiredness or fatigue followed by an extremely low mood, I end most of these days by crying from how tired I feel.

Anyone else been through something similar? Some days it is so bad that I sometimes think I might have some type of cancer, tho I do not have any visible signs like bumps, discoloration or whatnot.
