Problem connection : Timed out

Hello, for last few weeks ive had some issues connecting to any server, when i connect to the server i can move around but its verry slow when i press e to open up the inventory or even any gui i click on.
When i i break any block the block its self does not drop, then it disconnects me.

Ive tried everything
ive checked java its self (mac)
ive redownloaded everything
ive checked my firewall

and still nothing is working

could someone please help me and reply please
