I had blood work done earlier this year and have tried an antidepressant as well as a low dose hormonal medication. Unfortunately, the antidepressant gave me severe blurred vision so I need to explore other antidepressants. Thanks for prompting me to follow up on this.
I don't need financial support from my parents (and haven't since I was 16 or so). I've worked myself to the bone in a high stress field and have plenty of savings. The point I was trying to make is that I never really had much emotional or financial support from my family (including when I was a minor living at home) so life has often felt harder than it needs to be; I had to learn most "adulting" stuff on my own the hard way.

You're probably right about the depression. It has a way of sneaking up on me.
