I appreciate that - exactly this is something I've been working on, and a lot of the time it's fairly successful. But this is the ADHD curse - it's all too easy to feel rejected and lonely because on this occasion I have no plans with anyone. The negative thoughts manage to persist much longer than the positive.
The Now always takes precedence, always dominates.
I have a Fairphone 4 with LineageOS - it's a couple years old now but runs great. The headphone jack situation was an issue for me too, but I bought a USB-C -> 3.5mm converter for a few euros which now lives in my headphones case, and honestly, it doesn't bother me. Don't let that small point keep you from a good device.
