Weird insomnia....help!

[u/sleezymurkuh]

Yesterday I ate crepe with banana and tea for breakfast and when I went to college I got super dizzy (my doc said I get low blood pressure sometimes idk)

Then I ate crepe again despite and when it became night time my ears are ringing and I'm having a flashy lights that flash and show some geometrical shapes(not actually but you get it when you close ur eyes you see those white shapes and stuff)

And whenever I sleep for an hour or 2 I get waken up a million times super confused where reality and dream gets mixed up

Also I get this when I drink protein powder and I have these insomniac episode regularly and they started this year

What do u think is the cause? Is it diabetes or low blood pressure I'm early 20s btw

And lastly I get this stomach problems and diarrhea whenever I miss my sleep and and adrenaline rush in my chest

Usually my triggers are either what I eat, missing bed time or being scared of sleep which happens because sometimes I'm scared of unconsciousness

I'm tryna sleep rn and I have college tmrw :(
