Hello Reb! Welcome to Susan's.
Glad you joined. You don't have to say or decide whether you are MtF - this is a place for everyone transgender and that includes those just starting to understand and explore, and also those of us who are non-binary. Several reasons it's called a gender spectrum, your answer and goals may change over time.
Software penetration testing (security analysis) is quite a skill - requires a blend of creativity and technical aptitude. Great field to be aiming for.
I found a wealth of information in the Wiki section here on Susan's when I first joined. The main thing is finding so many super helpful people in different stages of a common experience and being able to interact now that you are a member.
Something else to consider is getting access to a qualified gender therapist or counselor. Having one definitely helped me. You mentioned being bipolar, I am not sure if you are currently working with a health professional but they should be able to refer you to a gender specialist. A significant number of people in this community have found they were able to reduce or even eliminate the need for other forms of medication after starting HRT. Each of us is unique so we shouldn't always assume that would be the case, but it is a potential benefit.
Susan's Place has information we always provide to new members, and I will add it here for you. This helps keep everything running here as intended, and can save you time as a reference.
