I hate to see you in pain like that. I know all too well what stress, anxiety, and all that stuff feels like.

I'm not the best at this kind of advice, but if I had any suggestions, I would say maybe you could try to do some sort of work for your parents (chores, huge favors, manual labor, making something, something of that sort) in exchange for them giving you the opportunity to see and heavily document (photograph, video, or whatever it is you would like to do) those traffic signals that may be getting replaced soon. I remember when I was younger, I would often do big things for my parents in exchange for money and stuff - my most vivid memory of this sort of thing was lifting a large amount of huge stones (probably at least 50) into my grandfather's old box truck in order to haul it to our own house and use it as landscaping decoration in our yard, and I helped with that as well - so in return my dad gave me $50 or $60 and with that, I bought a video game - Mario Kart Wii to be specific (in 2011). I'm not saying you should lift stones necessarily, but you get the point, that I'm guessing it may be possible that if you do something huge for your parents or such, they may return the favor and get you to the traffic signals.
I feel your pain as well, so I know how you feel. It is saddening to see old, very interesting road-related stuff go away in the new age, such as state-name Interstate shields, truss bridges, button copy, and the sort. Change is a part of life, but change can be hard. But we all got to do what we can to roll with it.
