Frustration

So I’m feeling really bad right now. I really don’t know how to feel at the moment. I’ve had this frustration literally build up in me for years now. I think I let some of it out today.. my husband and I have been trying to get pregnant for about 5-6 years now. Today, two close people found out they were pregnant and came to me for support. I showed I was happy from the outside, but then I started just bawling. Has anyone else really went through this? If so, how did you make it through it?
