You're not alone in feeling this way! I was diagnosed mid September, and I cried every single day. Anything could trigger tears streaming down my face. I am finally starting to accept the cards I've been dealt. I have highs and lows, and that is normal.
However, I just wanted to share what has helped me in this short period of time. I started seeing a therapist the week after being diagnosed. She creates a safe space and validates all my feelings. I also attended an in person support group that meets once a month. I'm not sure where you live, but there's got to be some in your area! At the meeting, I met a girl who is a part of these secret facebook groups for people with H ... apparently there are a lot of them! She invited me to a meet-up for one of them ... just people from the area all with one thing in common. It has made me feel not so alone and realize there is life after this diagnosis. I met one inspirational girl who is so open about her status and wants to do her part in trying to end the stigma. There is hope ... you've got to just use all the supports around you to make yourself feel better. For me it's being around people who also have H who know exactly how I'm feeling/my daily struggles.
I know it's hard, and I hope my story helps. Giving you hugs because you are not alone.
