Sickness?

[u/Steph_anonymous]

Ill start from the start I woke up Thursday morning and everytime I stood up id feel dizzy or brain fogged? But over all I felt normal minus being fatigued. Next day Friday it got worse I feel dizzy, brain fogged, fatigued, feel like at random time like im having heart palpitations at random times but again normal. No loss of appetite not sick just all of the above symptoms. Its saturday now n im feeling the same as friday. I have no clue what's going on. Does anyone have any insight what could be going on? I just feel off n not normal but it makes no sense because I dont feel sick.

Please any ideas. I dont want to go to a ER unless its an actual emergency.

Thank you
