So dear! Thanks! I don't know if I'll go on vaping. Buying a mech is a good idea, and the K100 is dirt cheap at FT. I have to make up my mind, either I smoke and give up buying vaping toys or I do vape all day long, for which I'm willing to dig into my savings and get me some much needed things, a Provari included... Don't yell, but my mods failing have made me rethink the Provari thing...
Personally, I don't think in absolutes, either/ors, black and white. There are too many variables, most of which are beyond my control, and I'm constantly reevaluating my perspective, so it may change when things are looked at from a different angle.
Please excuse me for being blunt and I hope you don't take anything I say personally. I'm free-associating here.
You are going through a time of extreme stress, which it appears is beyond your control. You can, however, distract yourself from that stress by focusing on the stress of trying to choose vaping or smoking, which theoretically is within your control, This kind of stress has the added fun of being able to beat yourself up over not being able commit one way or the other. In the big picture, stress can be very physically damaging.
Now what can you do....let's see...
You can stop buying vape toys. It sounds like you are looking for the perfect vape - let me know when you catch the unicorn, I'd like one too. A ProVari is just a battery tube. A very durable, consistent power source, but that still leaves you trying to find the right tank, carto, RBA, whatever. I'm trying to think simple, simple, simple.
I would recommend a Reo, it's just a battery, an atty and a bottle of juice, but you have one already. What was it you said you don't like about it? The Reo is a nice mod, very simple. I think it might be more cost effective to figure out how to make it work for you, instead of spending money getting another battery device and basically starting from scratch trying to figure out what toppers will work with it. I haven't had my Reno mini very long, so I'm trying different attys to see what I like, but I can state for a fact I have spent less money on attys and cartos to experiment with than I have on tanks for the ProVari.
Again, I'm just typing what's floating through my mind at the moment. I'd like to help you be less stressed if I can, but I am not you nor going through what you are, so I don't know how you feel and I may be completely off the mark.
