CMAXB, sounds like you would like to contiou your usual routine while the lifeguards are getting more worried at the same time.
I would suggest to you to get a buddy or two,, so you can watch each other. Also follow a freedive course, get a paper stating you both are able freedivers. And with patience build up (earn) a trust relation with the lifeguard(s). Be helpfull, appreciation, and slowly educate them a bit etc. Many Lifeguards have problems with the mandatory skills of UW distance swimming and picking up a doll from the deep, equalisation, trade your -expertise- for their trust and exeption twards your beloved passion.
Avoid force, let them be in control of helping you out. Listen for their worries and whishes between the lines! - basic people skills.
But above all know what you're doing, and dive with a buddy!
And if you're allone, only do strenght, stamina and technique.
One little idea to get a buddy quickly, carry a monofin to the pool, many people love to try one!
Joining a scuba club is very easy, they are usually in need of happy active members and they surely are intrested in your diving skills.
Let us know,
Love, Courage and Water,
