@op, losses is one thing traders cannot run away from, so you must take risks management seriously. Keep learning to improve your trading skills and with time you would get used to everything about trading, including losses.
One can't run from losses in trading, however, one can learn to deal with them and turn them into a positive thing instead of allowing them to spread negativity within you. What I mean by saying that is that when we lose money in trading, we should try to find what mistake we have made which caused that. If we manage to find the mistake, we should work on it so that it doesn't happen again, and if we can't find the mistake, we should reevaluate our trading strategy and start from scratch.
Starting from scratch means that you should either adopt another strategy or work on your strategy again and make sure that your strategy is working the way you want it to work. If it isn't, it needs to be changed.
To handle your emotions after losses, you should take small breaks from making trades, and in that time, you should only watch the market and try to gain as much knowledge as possible.
