ive been in treatment for my bpd for months and have had amazing results but, recently i got ahead of myself and went into a rage impulsively sending some crude texts over a misunderstanding and i truly feel terrible, and truly so sorry but i've never been one to feel comfortable apologizing and i've been avoiding his messages for days already which is just adding on the anxiety and panic. what do i do? is it just too late at this point would he even take my apology?

tldr; after a misunderstanding i was sent into a rage and sent some crude impulsive texts. instead of apologizing i've went ghost out of fear of confrontation and vulnerability. advice?
