I didn't read it as though you were looking to sell all your gear. Don't, I think you'll regret it. Maybe keep a guitar and a bass as one day you might want to pick them up again, and you won't have anything to play. Periods of 'being over it' for whatever reason seems common, and I went through a few years of not being interested in playing. Then I picked it up again, and quickly moved from 5, then to 6 string basses, a path I would never have imagined taking a decade ago; fortunately I kept most of what I had through the down time so I could pick up again easily enough.
Though I have some guitars, I'm not very good and have started lessons and am finding it fun. Mostly, frustrating but good. Never know what the future will hold.
Whatever happens, I hope you come out of it OK.
For me 2019 to present became my bucket list of what I wanted to do on planet Earth before I go as no regrets. I was my Dad's caregiver (he was 96+ yo, the dog was 18+ yo), I buried both of them in 2018 as they passed away within 21 days of each other, Mom had passed away 5 years earlier, 21 & 42 days from dog & Dad in that order. For all 3, I shoveled dirt at the cemetery burials, was the least I could do as final respects. Also made sure I was close enough to visit for anniversaries & holidays. It took me that to realize what was most important in life. I'm not done yet for what I still need to do.
When the dog passed away, Dad didn't want to do anything fancy, but she was Mom's dog and I knew the right thing was to return her to Mom's side. The crazy thing about it all, a couple of days before the Euthanasia appointment, the dog had enough strength, I took her to the cemetery for the 1st time the animal ever was there. Completely blind the dog was leading me thru the cemetery to Mom's headstone and she stopped, she sniffed the ground, then laid there and I knew that's when she was choosing her final resting place. On the drive back, this dog that had never barked, she was howling in the front seat & didn't stop until she was back inside of Dad's house and she immediately went to his side, the chair he always sat. For the Euthanasia, I made sure I paid for the private cremation ashes for the dog that are returned to the owner(s), best $ 100 additional upgrade that I ever spent. I buried her ashes at midnight of a full moon there. The next day, I told Dad what I had done, and he was grinning from ear to ear, said to me, Well, you said you were going to do that & you kept your word & did it. A day later Dad went to the ICU for 5 days, 5 days after discharge, he passed away. And it was my responsibility to get the WW2 Vet headstone done, bury his ashes for the 3 of them to be reunited in their final, right size retirement home. Their declines coincided. The dog had gotten Dad thru the final 5 years of his life, just as he was making sure she was taken care of after Mom's passing, they both knew it was time to be with Mom.
