Jamie-Lynn Sigler and pro baseball player Cutter Dykstra only got married a few days ago, so when the former "Sopranos" star decided to reveal to the world that she has been battling multiple sclerosis (MS) for the past 15 years, it was incredible to hear how supportive he has been and how much this played a huge role in her decision to open up to everyone about the disease.

"Jamie-Lynn's a very positive person, bubbly, upbeat. She's not the type to wallow in self-pity or feel sorry for herself or go into hiding. [The fact] that she's handled her diagnosis so gracefully isn't a surprise," a source told E! News. "Her relationship with Cutter is strong. She's got a big support system in him. She's looking to work more, but I've also heard they're hoping to add to their family again soon."

Sigler, 34, and Dykstra, 26, who have a 2-year-old son Beau together, were engaged for three years before they got married on Jan. 16. Sigler recently revealed that she was diagnosed with MS when she was 20 years old, but that she wasn't ready to tell her truth until now, as HNGN previously reported. She explained to the magazine that even though the disease came as a shock to her at first, she credits her husband and son for giving her the courage and support she needed help her get through this and live openly and honestly.

"I'm at a point in my life with my son, with my new marriage, it's a new me," she told People. "I don't want to hold a secret where it feels like I have something to be ashamed of or have something to hide. It's a part of me, but it's not who I am...I didn't want [Beau] to get to an age where he felt like he had to keep this secret for me as well. I wanted to be an example to him of strength and courage."

She also explained how she doesn't know what the future holds, but she's "excited for the first time in a long time." "I've got my brain and my heart and I've prepared myself for everything that could happen," she added. "But I've got an amazing husband, the best son and I hope that we can make more babies and just keep having fun I'm the luckiest girl in the world."

"Words can't describe how proud I am of you," Dykstra tweeted on Wednesday. "You truly are my hero. I love you so much. @JamieLSigler."

She also posted a touching message to Instagram sharing some of her story, thanking People for allowing her to share her story and once again, thanking her husband and son.

"And an even bigger thank you to my husband, my son, my family and my friends (who are my family)," she captioned a photo. "You all have fiercely protected me over the years when I was too scared to share this publicly, for fear that everything would go away. You stood by me, helped me when I needed it, and always made me feel loved and worthy of things even when I felt less than and different. I really am a lucky girl and I can't wait to see what life has in store for me now that I can finally live my truth."
