You don't have to choose one or the other. There are thc strains that control anxiety pretty darn well. Try blue dream and or Colombian gold. Both help patients of mine deal with anxiety. For an indica try cherry pie, and you'll be a mellow fellow. And yes you can mix thc and CBD with good effect. A pet peeve of mine is people thinking adding CBD takes something away from thc. IMHO it enhances the experience rather than take anything away. It's hard to define how you feel on CBD. A lot of us feel nothing definable, it's more like a lack of pain/inflammation than something you can spot. For me it's ussually later that I realize I did something and don't feel like I would have if I didn't have the CBD. That and I focus better when on CBD. Instead of wandering around in circles forgetting my next step while doing a project, (thc) I get right on it and stay focused when on CBD. It's hard to over estimate the role terpenes play. They may be the most important part, or at least an equal partner. If anyone askes about specific strains they might like, I ask what strains they like now, and suggest they research the terpene profile and go by that. For instance I don't care for the peppery or earthy tasting terpenes, but love the citrus or fruity types. Follow your nose, lol.
