was thinking of posting a question similar and found this post. nice
If you always ending up losing when your stack when it gets to a certain point, you
have a leak.
Sounds like you've already identified your leak. You can either work on fixing it or set a limit and stick to it or keep losing your chips.
Im working on the same issue. At the present when I get that feeling of worry. I leave. Its the same feel as being at a game my BR doesn't support.
Im hoping as my BR grows that feeling will gradually diminish. Also working on my deep stack play.
Hope this helps. Ty for the post. It has helped me
