I’m sorry to hear that. It often gets much better with age though! I’m 29 now and I can eat most stuff without feeling any aversion. It’s more that I prefer my safe foods but I can thoroughly enjoy other meals too. Cooking can still be tricky sometimes but I don’t let that ruin my diet. I hope your son can find a calorie-dense safe food. My go to in that regard are almonds, cashews, peanuts, pumpkin seeds and if all else fails gummy bears.
Therapy and making my peace with the past. Like working through it and then actively deciding to focus on the present from now on. This video actually kicked off my healing process.
I just keep a Windows partition on my PCs for those few occasions where I need it. Usually about a tenth of the drive. For most stuff you can mess around with a vm or wine too but this way is easier imo. And realistically Windows 10 will be fine to use for the forseeable future. It’s still possible to use XP securely even today.
