If you're asking the question then the answer is probably a yes, you need something but is that something therapy? That's much more difficult to answer based upon what you've provided.

One problem with the average psychologists and therapists in general is the adage of "when the only tool you have is a hammer every problem looks like a nail." There are the chances you may find a good one who may have a broad scope on understanding that not all problems can be solved through their specialty. I myself would focus on measurable testable results as you fall into the age range where hormonal imbalances can grow to the point that they are affecting every aspect of your life. Doing this before or at least in parallel with seeing a psychologist would be beneficial.

I can only express this as a personal story but when I was in my mid-40s I could describe all of the symptoms you are mentioning. Then on top of the general listlessness my wife divorced me for reasons that to this day I don't truly understand. This just started spiraling down into a depressive state. After about a year of suffering with this and hearing for the millionth time one of those men's ads on the radio I said what the hell and went to one of these clinics. They draw blood they do measurable testable results to determine your hormone levels and it's clear to see that you may have a measurable fall off or you may have some other underlying health condition that's affecting things. This single thing of responding to one of these spam like ads on the radio was, I think, the best thing I could have done. Then my testosterone levels were sub 300 which is at the levels where insurance will cover you for getting it boosted. Within 3 months of nothing else changing in my life except going on trt my entire outlook changed. I was no longer depressed about being alone and I was still alone and I'm still alone to this day. My focus at work is back. My ability to take on physical tasks is honestly as good as it was in my twenties. I'm 50 years old now and trt is put my levels back to the normal range and I can work all day on the computer writing software and then work 6 hours in the evening on the house remodeling and wake up the next day and do it all over again. The mental focus and clarity is amazing. So again this is 100% a personal anecdote but being tested is a very small cost because the symptoms you describe as I said I could have listed those same symptoms. Not all clinics are the same but they all sound like they're just pushing some snake oil, which I'm not sure why they advertised that way but for me it was not snake oil.

At minimum getting hormone levels checked and getting a baseline readings of where you're at now compared to normal ranges is a basic thing. You also don't need to go to a men's clinic to do this because again that's a specialty for them so whether it's slightly below normal or very much below normal like mine they will find a way to try and sell you on their products. Your regular doctor could order these same panels you could actually go and pay for these yourself and get them privately it's only a few hundred for lab draws and results. It's certainly worth checking at least in parallel with any kind of a psychological therapy.
