<human>: Give me a shortened version of the text

I've been dating my girlfriend for almost a year and we fight every few months for the same reasons. Basically I work too much, get way too lost in stress and I'm not confident enough.

These are the causes of many other issues--I pay less attention to her, I show less affection (especially in public), I don't often initiate sex, we don't spend enough time together and sometimes she feels like I'm not on her side when she's having issues with friends and stuff.

We're insanely in love, we have great sex and we want to be together long-term. The problem is that when we fight i realize how lost I got in stress or worrying that I'm not good enough or that she likes someone else. I snap out of it for a while but then I go back to working lots, not having a lot of confidence, worrying and all those other issues come about again.

I really really want to break this cycle but I find I just get sucked into this negative pattern over and over again. 

What can I do to remind myself to be present in my relationship and life, and not let my lack of confidence get in the way of initiating sex or showing affection in public, and not take on extra work? 

I haven't done much to ensure I stop getting into these patterns. I find if I tell myself to do something like read an article about sex every day to remind myself that I need to be more confident initiating sex, I don't follow through. 

I'm looking for strategies.
<bot>: I get into a pattern of worrying, working and having low confidence. Me and my girlfriend fight, things get better then I go back into that routine. How can I stop?
