Working out advice?

So I'm 9 months on T and I'm naturally pretty scrawny. Dad and cis brother are the same. Fast metabolism shit. But I'm the only vegetarian in the house and generally eating can feel like a chore. I work all day and go on walks but between working and driving that doesn't leave me time to do the schedule I was doing before. I'm just not feeling confident and I worry that I might never get out of this body somehow. Lift a brother up and give me some advice for starting up again 🙏 I need it. I am scared of gyms and workout with a kettlebell at home rn but open to any suggestions.
