I believe low T has been a problem for a long time for me. Moonbeam, you sound very much like I was, trying to cope, but not having the energy reserves to do so. My husband and children had to deal with my unpleasantness due to exhaustion. Be kind to yourself, don't beat yourself up, but do be honest with your family what is going on, so they don't think it's about them. I say this because my Mum didn't and I grew up thinking I was the cause of her mood swings. You're younger than me, so you have time to seek out the appropriate help.
I'm aware of the disadvantages of implants. Not a decision to make lightly. If only the patches were still available. It sounds like they will be very thorough though. May have to have a scan, at a cost of course, but may be good to know that all is well.
