Getting back into a hobby to get away from another frustration doesn't always work, cause then your heart's not in it. That's just escapism.
Sometimes the desire is just a matter of achieving momentum. I've let my hobby desk collect dust (figuratively speaking; my OCD wouldn't allow it) until I come across something that piques my interest and I plug in Ye Olde soldering iron and fiddle around. Might do that a few days, fall into a lull and then suddenly pick up and follow through.
You may want to look in other areas. I was "collecting" watches[1] for years before I realized that I wanted to make watches. Because there was a 'purpose', I found myself with a desire to do more electronics projects to support my hobby.
My knowledge in that area (and software) gives me the leverage to make cheap-but-adequate tools that would cost $15-50k or more from watchmaker tooling companies.
[1] Basically, using my annual watch "budget" to buy a watch that had some unique or unusual attribute, not really collecting in the traditional sense.
I wish I still had the desire to just play around with such things again... :-\
