My story - need support - husband cheated

[jmtp]

I am sure it is normal to feel like I do but I want to make sure and see what you all might have to say about making me feel better.

At times I literally ache - my whole body just hurts.
I have no appetite and this is sooooooo not me.
I feel like the world is on my shoulders.
I get very mad...then desperately sad.
I feel alone.
I feel scared.
I feel confused.
I think I have had a least one anxiety attack....I physically begin shaking and my mind races with every bad thought you could imagine.
I can't focus on anything but my relationship.
When husband is gone during the week I can't think about anything but what he is doing or who he is with.
I am obsessed with my phone/email. In case he calls.

All this makes me seem pathetic and weak. Rarely, I will have the feeling of strength or calmness. Everybody that knows (which is only 3 people) keep telling me I am a very strong and wise person. But, I don't feel like it.
