Hi P ,
I am not a doctor , however I would classify you as mildly to moderately depressed, and possibly slightly anxious.
Are you see a therapist ? Do you have the means to see a therapist , if so they can be a great help.
Your BM`s are normal , your heart rate is fine , you should however brush after every meal just to save your teeth if nothing else.
Can`t sleep , could be either or.
You seem to be concerned about your BM`s , don`t be they are fine.
Have you talked with a doctor ?
Here is my advice , carry on and see if your condition get worst , you are not in a trauma state now , I can tell you that.
Also it is normal of bowel consistency to be a bit off , and your heart can withstand beating 200 BPM for one week straight . and you would feel no pain , you would notice your heart racing , however it would not cause any permeant damage to your heart , it would feel strange yes , but painful no. It would scare the pop out of you and most people , but in the end your would be just fine.
I think something happened in your live recently that is causing mild distress and that is leading to your symptoms.
My suggestion , see your doctor or stop by a minute clinic , get the word from them. If you are still a bit off seek out a therapist if you can or just talk with a friend or close family member.
Of course we are here to help as well !!

So glad you stopped by.
Lighten your load , you are fine , but just get checked out !
Take care ,
