Hello Monique, welcome to Susan's!
I don't have a good answer for your question regarding inheriting transgender characteristics, but I believe the most important thing is to determine who you truly are and make the best possible long term decisions. Some people view being transgender as a negative thing, but this can also be viewed from a positive standpoint. Some people who are intelligent and open minded may have a strong desire to take control of their own future.
I am sorry to hear you lost your father in an accident.
We have quite a few members who found they were able to reduce or stop anti-depressants after HRT had enough time to take effect. And we have members who have found they require both. This is an individual decision and should be based on your personal requirements and a doctor's care - just some additional information to consider. Based on your recent history I am glad you are working with a clinical professional and I hope you can find true happiness.
I am MtF in the US. When I came out to my parents last year (they are very traditional) I explained myself this way: biologists think roughly 7% - 10% of humans are left-handed. In many countries the incidence of left-handed individuals has varied historically, sometimes less than 1% if nobody was allowed to be left-handed. My 86-year old father thinks he might be left-handed but isn't sure. When he was a child he was hit on the hand repeatedly any time he tried to write with his left hand. When I explained transgender people face similar issues (although more severe) he suddenly understood my point. People should not be ashamed of being left handed, or transgender, but society is only starting to understand the medical facts.
We have members who have been able to maintain an existing marriage, but also cases where the other partner would not agree to the change. Children make the decision more challenging but I have seen strong family connections maintained either way - it is possible if everyone communicates well. These are difficult choices but my advice is to visualize the future. If the current year is 2023 or 2028, what decisions will you wish you made in 2018?
Monique, a warm welcome to Susan's - and I am so glad you are here.
All the best,
Kendra
