Yes, I had the exact same problem. One of the side effects of autism can be depression. That can certainly make it hard to be "up" and happy 24 hours-a-day. Thankfully, eventually I was diagnosed with Severe Depression, and put on medications for it. They have helped me a lot! Being a man with autism is probably even more difficult than women have it, because in our culture men are supposed to "suck it up" or "laugh it off" when they're depressed. 🙂 You may notice that in the past year, several professional basketball players in America have published articles in "The Players' Tribune," in which they reveal that they have had severe depression, despite their fame, adulation, and riches, and I think it really got the attention of the American sporting public.
