Here's my stance. The best "fix" is to learn to accept your stammer. Learn to stammer in front of other people and not feel bad about it. Maybe it'll improve, maybe it won't. The point is, you shouldn't care either way. That is honestly the best fix someone in your position can hope for. (And a lot easier said than done, admittedly.) If you want fluency as a goal, then a speech therapist, group therapy or a therapy course is a must. However, as someone who has genuinely given speech therapy my all (tens of thousands of £ and thousands of hours of my own time over the course of my life), I learned the hard way that no matter how much control of my speech I achieve, there is no guarantee that my stammer won't come back worse. For some people it works, and, for others, that is time and money that you'll never get back. I personally wish that I'd spent all that time (and saved all that money) coming to terms with my identity as someone who stammers. The good news is that it's perfectly achievable, unlike fluency or controlling your stammer. Here's a story for you about a friend of mine: he grew up with a moderate/severe stammer. When he was 13/14, having endured bullying and the like, he made the decision to "beat" his stammer. His parents got him a speech therapist to give him the techniques he could use to control his speech, and he entered himself into every speaking-related club he could find, including acting, theatre and debate clubs. It was difficult at first, but he actually did it: he "beat" his stammer and simultaneously became extremely eloquent. Using his therapist's techniques, he gained control of his stammer to the point where he was winning debate competitions and no one would have been able to tell he had a stammer. When he started university, he was a public speaker in his spare time: he was invited to give speeches and interviews for radio and podcasts and was even paid for doing so. Then, on one occasion after leaving university, he was giving a speech at an event and then, for the first time in almost a decade, experienced a long block that he couldn't cover up. After that speech, his stammer came back with a vengeance. The invites to speak at events and interviews dried up pretty quickly. The speech therapy techniques no longer helped. He had no choice but to adapt his stammer into his "normal" way of speaking. He currently has a very obvious stammer (a speech therapist might describe it as moderate or severe), but he worked hard to incorporate it into his public speaking personality so that it didn't come across as unintentional. He acted like he wasn't ashamed of it. Not all of the speech invites came back, but a lot of them did. If you want to go for fluency, that's entirely up to you. Maybe you won't end up like my friend or like me. But it will be very difficult and it will require a huge amount of time and effort. And maybe you'll reap the rewards of your hard work. Or maybe you won't. Or maybe you will, and a few years down the line, you'll end up back at the beginning again.
