I don't know your approach. But If I were you I would decrease own size of trading. Try to trade micro contract (in case futures trading), or use less size in options. The fear and regrets which you have right now (about big losses) might conduct your opinions. If you decrease your losses till 10-20 USD per trades, you might be not so worry about it and it helps to develop better your trading skills.
This is a good idea. I have told myself multiple times to just trade the micro contracts to get back on track. Usually that works for a little while and then I start thinking "why not scale up?". Probably the most destructive thing though is if I am down slightly (say $100 or so) I start to think "hey one quick scalp on ES/NQ could easily cover that loss". Sometimes it does just that, and then other times it makes it 2-5x worse. I think I either need to stick with a single micro contract until I can learn to control my impulses or swing trade. I tend to do better at longer term options trades anyway (SPY or SPX). These futures contracts are so choppy that I often get faked out and abandoned my position too early.
