What should I do with my twitter?

[rirry]

I think I got hacked on twitter because when I log in to twitter I see these tweets that I didn't send,saying something like ''Is this you from a couple of years ago'' and there's hundreds of tweets like these on my twitter which I didn't send and people are getting angry at me because they think it's me.I can't send pictures through Direct messages I can only tweet.I have another twitter which I made just a few weeks ago and I can't send pictures on that one as well,I don't understand so even if I delete my old twitter I won't be able to use the newer one because I can't send pictures through DM,I really don't know what to do.my computer is a lot slower now,what should I do??
but why won't let me send pictures by Direct messages to someone??

You need to change your password to the very complicated one. Just use below link to create one:
1) http://www.pctools.com/guides/password/%20/
2) https://identitysafe.norton.com/password-generator/

And then log-in ...

Hope this will help to solve your prob.
thanks!
