I would post your labs because you seem confused about the difference between LH and Total T.
This is a common symptom of low-T.

If your Free T is low, then your testosterone isn't at a good level. Also you can experience symptoms sooner than these cutoffs, because no consensus has been reached showing a clear threshold for TT or free T defining a testosterone deficiency.
The UK (NHS) is still in the stone ages with regards to male sex hormones.
You need a private clinic like Balance My Hormones or Men's Health Clinic.
