a good therapist, on seeing a person come in and say "I'm troubled by this problem", will see if the problem is fixable. If you're super stressed because you're working 60 hours a week, your therapist should say "stop working 60 hours a week, and here's some techniques to ease the symptoms while you figure out how to stop doing that".

Bad luck dating is only somewhat fixable, since you can't control the minds of others. So a good therapist should push you to get better at dating if that's what you want, but also help you to become happier being single. (Drifting off-topic, I think being happily single is a lot easier after you've dated a bit, and now have the self-confidence that comes from knowing you could get laid if you felt like it but don't want to. Which may be one reason why single women are generally happier than single men. I hope this doesn't come across as mean but I'm clocking you as a younger, relatively inexperienced dude?)

My current therapist encourages me to trip shrooms and explore Hegel because that is what works for me. If you find a good one then they will quickly realize the traditional line of advice isn't what you're looking for. That said, I've also seen my share of awful therapists so I understand your hesitancy.
