I recently was given a very generous offer from a well known company (Company A) that I was thrilled to get. At the same time, I was interviewing with job B, which was taking some time, even after mentioning other interviews, since people were out of office. I got an offer from job B, but it was a third less of Company A. When I spoke to the recruiter, I mentioned my other offer and that I would like a more comparable salary. I offered (she didn't push) to prove that I had the salary I was asking for from Company A. Then, I did probably the most stupid thing I have ever done. I took a page from my marked confidental offer letter from company A and forwarded it to company b as proof-I didn't want them to think I was lying to try to bilk them for more money.
Now, I am completely terrified I will lose both offers and, perhaps, I deserve to. Company A will find out and rescind my offer for not trusting me (which, I suppose, they shouldn't) and Company B might realize I'm a total fool. I did this in good faith-I really loved both teams/companies and I didn't want to reject Company B because of the lower salary or make it seem like I was lying for more money but I really overthought it. I'm scared company B will email someone at company A and I will lose both offers. Please help.
