I Feel Useless

So, I am 7 months on T and my gf moved into her own place and things needed fitting like wardrobe and washing machine and lifting furniture. The thing is I am strong and can lift things but big things like sofas and washing machines I ac cannot do cause I’m really short and my hands are very small

It’s really embarrassing my gf seeing that I am struggling to carry things. I can easily pick things up but big things I struggle with immensely. Nor can I put together a wardrobe from scratch with no manual. All the men in her family were able to do that and I really wanted to but no one would let me help. So, I stand there and watch with my gf

Growing up I’ve never done those things. I wanted to but my parents raised me as a woman so all I’ve done is cleaning. I’m good with tech. I can fix laptops, gaming consoles and controllers. But every time it comes to furniture I fail and I don’t feel like a man at all

Tomorrow I have a chance to prove myself fitting a shelf her brother has left the drill and screws. I’m stressing cause I don’t know where to start and scared I’ll mess it up and her brother will have to come and do it. I just want to be able to prove myself I can do something manly

Is it normal to feel like this? How can I get over this? Do other transmen feel like this?
