Therapy can be good, that said it is also good to talk about stuff to a friend or some anon on the internet.

The difference being in the effectiveness of each method but generally just talking about stuff will generally improve your mental state.

Just be careful not to get caught up in a echo chamber that makes you believe that you don't have a problem and you're good.

With all that a therapist who is very good might be a lot more effective that the other methods, emphasize on the "very good" part but they also charge for it and a bad therapist can also be far more damaging.
