Instant tears and anxiety

Does anyone else get instantly tight chested, nauseous, and pursed lips while trying to fight back tears when your significant other snaps at you? Not only are he and I to be married in May, but we are business partners on a new venture. To say the least, money is tight, stress is high, and we both have a million and one things constantly going through our minds....our relationship for the last year has mostly consisted of talking about the business and once in a while remembering we are more than just business partners.

Someone please tell me they’ve been through something similar and things got better?! Please tell me all this will be worth it...I don’t know how many more emotional beatings I can’t take before I snap.
