I say this with kindness

:
I do not think your issue is the trading strategy that you are using, but rather the fact that you are risk adverse, second-think your trades, and switch your behavior as the market moves.
Regardless of how you trade, those aspects of your personality will remain and may only go away with experience.
Not that it's bad. It's better than being so gung ho on risk you bet the farm
What it does mean is you perhaps want to look at strategies where your max loss is acceptable. If you enter a trade and know the absolute maximum you can loose is so small you won't bat a lid at, then you are less likely to reverse that trade and be sad you pulled out so soon.
Simple example, if you paired each trade with a stop loss or option such that your max loss was 10$/trade. Then you are unlikely to pull out. You can go do other things, sleep, whatever, and know you got nothing to worry about.
Find your warm-fuzzy point, and trade accordingly.
