Yes they do get easier

Hold in there. The longer you go without the easier it gets to deal with. Of course I still have times when I have an urge, but the majority of the time I can talk myself out of it.
I will think about those I would let down, how upset my partner will be, I'll read old journal entries about how annoying and uncomfortable it is to be healing, how I would have to hid it from my friends and work mates, then what about if it gets infected? What if I have yet another longterm painful scar? What if a another skin growth comes up as a result of the cutting? These are all very real and very possible outcomes. What are the pros and cons of using cutting to relieve your symptoms? Its really a quick fix with more long term problems than solutions.
Yeah its easy to say all this stuff, I know it is much harder in practice. What about instead of self harming you self nurture? You're struggling right now, if you saw a child was struggling would you hurt them or help and care for them?
