Please Advice, What to Do, Restraing Order?

Biploar ex boyfriend is making my life a living hell.

I wish I could rewind the hands of time

he was so nice just days ago

now, he is mean, vindictive, really out of control

i am scared of what to do

i do not have any proof, just my word against his
a he said she said thing.

I am scared

i just want to be left alone forever,

we broke up, leave it at that, I pray he will understand this.

If I get a restraining order, I feel it may make things worse
if I don't, ugh

he can turn things on me, although there is no proof of me doing anything wrong, I did not do anything wrong
except love him and put up with his !**@!

ugh, my life sucks, his bipolar or whatever his problem, man

he threatened to call the cops on me, but the cops did come
just the whole thing, I do not want to be a part of, ugh

man,

insanity is doing the same thing over and over again, expecting different results,
i just want to start my life over,

man, why did this happen to me? No one deserves this.
