I struggled with this for a long time and even considered redoing my shower to eliminate the glass because it bothered me so much. I tried so many different things, including a lot of the stuff listed here but the best solution I found is barkeepers friend (https://barkeepersfriend.com/products/soft-cleanser/). It requires zero scrubbing and leaves the glass crystal clear after. I don’t even bother using a squeegee anymore because this is so easy.
In my opinion, therapists are like friends. You’re not going to be friends with everyone you meet, in fact, you probably won’t want to be friends with most people you meet. It’s hard finding good friends but once you do, they make everything a little brighter. Just like friends, it takes time to find someone you really click with.
You’re right, they can’t fix your problems or your environment. That’s not what therapy is about. It’s more geared towards helping you recognize your own thoughts, behaviors, and patterns that are not serving you and adjusting them to serve you better. For example, a therapist might help someone to recognize the early warning signs and triggers of a depressive spiral so they can take proactive measures to prevent falling into a dark well of depression. No one can eliminate depressive episodes, but you can learn to recognize it and actively work against it taking over your life.
I hope that helps.
