Guys on T with seasonal depression, how's your mood been long-term?

Hi all! I've been on T since March (yay) and it's been going well, but as we get back into the colder months I'm starting to wonder how the next six months of my transition are going to go.

Winter is a hard time of year for me. I get sick fairly often and work nights, so I take vitamin D supplements year-round (extra in the winter since I'm in the north haha) and my family is always Full Of Drama in December and January.

I'm not looking to make any more medical changes right now, but I would really love to hear experiences from other dudes with mental health issues on their first year of T. I haven't had to deal with being an angsty teenager in about 15 years and I'm very out of practice with not taking my hormonal angst out on the people around me haha. Any survival tips? Is a sun replacement lamp worth looking into?
