Wife recently came out

My wife (MtF) recently came out as transgendered. Not really recently but like 8 months ago. We have an appointment in two months for a fertility clinic and she starts HRT a few days after wards.

She has been suffering from dysphoria super bad lately. I feel so helpless because I don't know how to help her.

Can anyone give me some advice to try to cheer her up.

We've both been seeing a therapist for 6 months but I can't help but cry Everytime I see her crying. I really feel like I'm failing her and I'm so scared that she's giving up on many aspects and I can talk to a therapist all I want but he isn't transgendered so he can't speak from experience. I just feel so flustered
