I am currently on subq T, I'm on what is generally a half dose, and I am seeing about the same changes as my IM brothers who were either slowly brought to a full dose, or were at full from the start. Everything is happening at the same pace. Some things a little quicker, some a little slower, which I imagine is simply me personally and not anything related to IM vs SubQ.
I was badly introverted but all of my changes are making me more outgoing. Definitely still introverted and that probably won't change, but my confidence boost has helped me be a little more able to talk to other people. My social anxiety is significantly better. It is easier for me to be in social situations. A combination of public speaking class and my confidence makes it easier for me to get in front of class to present. I am more confident talking to strangers- like small talk in lines at the cafeteria and things like that. I DEFINITELY have less social anxiety in general. I still get a LITTLE voice anxiety, however, part of it was because between 2.5 and 3.5 months my voice didn't change at all. But at about 3.5 or 4 my voice continued changing and that anxiety went away again. Sometimes I am still dysphoric about it, but being able to feel it change is good enough for me right now.
My dogs and cats; I have three dogs and two cats. I was also away at college for the first 3 months I was on T.
The dog I've had the longest. She got SO excited to see me again. She clung to me the entire time I was home for Christmas (which was a little over a month.)
The other two dogs: the younger of the two treated me the same, but became more clingy the longer I was there. He started to treat me more like he treats my step-dad. The oldest dog didn't immediately recognize me, but as soon as she did, she was acting just like before to me, if not a tad more affectionate.
My cats: The youngest cat didn't notice anything. I was never her person to begin with, my sister was, so nothing really changed. My cat on the other hand, the older one, got EXTREMELY affectionate. The longer I was there the more affectionate she got. She was SO happy to spend time in my lap or just in the same room as me even, she was so much more affectionate that I almost cried that I had to leave her at home to come back to school. She always preferred my dad over me, but now she seems to pick us equally.
