I'm sick of hearing "it has to come from yourself".

I'll try to be clear because lots of people don't get what I mean.

I'm aware lots of things have to come from myself. When I'm in a bad place and people ask what they can do to help I tell them nicely being supportive is the only thing they can do and everything else has to be done on my own. I know I have to be the one figuring out the issues I face in order to fight them. I know SOME things are supposed to come from me.
But what I expect from a therapist is to help me build strategies in order to fight those issues. And they always tell me "it has to come from yourself, I'm not going to tell you what to do".

And... I don't get that. Let's give an example.
I get a lot of anxiety when I have to face lots of people I don't know. Firts day of school, first day of work, those are times when I don't sleep, carry a heavy weight in my stomach and everything in my body tells me to run away and hide at my place, where it is safe. And that thing was the last I had to overcome in order to sign up for a weekly physical activity. I dreamt about it for a few years and when I had the money, I made my research. I still had this anxiety issue and I knew I would have to struggle. So I used a strategy I found online (see, it didn't come from me). To be very short: you have to count backwards from five and then tell yourself you're not scared, you're excited (because physical signs are the same). So I used that. I had a good night and I didn't turn back on the way to the first session.

I'm confused. I believe it is cruel from therapists to hold back this kind of strategies, saying we have to develop our own strategies. Let's focus a second on the results: thanks to this strategy that didnt come from me (I wouldn't have thought about counting backwards. I wouldn't have come up with this strategy on my own) I have a weekly activity that helps me both on the physical and psychological plan. I even chose a 9 A.M session in order to make sure I would get up at least one in the weeks. There is something positive in my life, something I can hold on to.

How would it have been better to be left without any strategy and not go to that first session as a result?

I don't understand. I would have lost such valuable time. I'm still losing valuable time because therapists refuse to share strategies with me, because they keep expecting me to develop my own.
I don't get it. I don't get why they keep such knowledge away from us. Why does it matters so much that EVERYTHING comes from us?

I just want to move forward. There are strategies out there that can help me do that. Plus, we know for sure those are healthy ones unlike those I tend to build up.

I'm not asking anyone to do things in my stead. I just want to learn things that will help me deal with my issues. How is that wrong?
