I feel that ‘buddies’ on the dive charters here provide a false sense of security - they’re out of reach, not paying attention, or poorly qualified.
So looking at your profile, I assume that you've been less than a year. Now I'm not suggesting that you are inaccurate on your description of insta buddies, but can you be 100% sure you are without fault?
Regarding skills. Things you can easily do. Practise to ensure your buoyancy and trim is good, make sure your basic skills learnt in OW are still up to scratch. For instance, can you do a mask remove and replace without fuss and while being neutral? How are you at kit removal underwater, shooting a dsmb etc etc? Do you still "scull"?
Diving is one of these things that takes a bit of practise, and while I'm not going to criticise you for being forward looking and thinking about things, I will suggest that you do remember to take baby steps and ensure your basic skills are really up to scratch.
Most self reliant courses require around 100 dives to hopefully ensure the person has reasonable skills and comfort in the water (although this is not guaranteed)
Make sure you're self aware and composed. If you want to be a solo diver you need to be able to deal with mino issues without flapping.
Sometimes buddies just need someone to take charge, I appreciate that some will always be to**ers but that's life. However often they've not dived with anyone of a decent standard - when they do they tend to fall in line, realising that they're not as good as they think they are.
One more thing, I urge everyone to take Rescue and when possible the basic tech course, so that they can become more of a thinking diver.
Hope that helps
