It's great you've identified what kind of losses affect you more than others.
What is important to realise is there is difference between pain and suffering. In poker, when we lose we all feel a pain. It's a natural response to losing money and part of being human.
A useful concept formula to bear in mind is this:
Suffering = Pain x Resistance
Resistance can be thought about on a scale from reject to accept. The reason you struggle with tilt is because you struggle to fully accept the result that occurs. The quicker you can accept the outcome, the better your mental well being will be.
How you actually do this practically requires a well though out method, that involves:
- Instilling different beliefs through repetition
- Being self-aware to realise your overall happiness levels before you play
- Having a useful method you can use when "tilt" strikes
- Understanding how you can clear up any lingering feelings
