dont know what to pick so i dont care

i dont knwo how to say this but i just started and as a gamer i found littrely a few bug my whole screen gets blank and i mean not that i cant see anything i cant see my inventory and where i even aim i even have a delay of placing then i just vanish same for attacking and those creepers keep exploding in that time delay, even when i light my whole island i stil get mob spawn on a freakin light so i dont have mutch fun building let alone even play normaly if the server is not even stable in the first place why even launch it its annoying and i mean servers like skyblock and others yesterday it even crasht a lot of times when u even have to restart building for a few min that u where busy so what gives even when u switch server that it will say every few min or so.......... when i play alone on my own little world it aint a problem but the servers sorry its the biggest bullshittery that there is sorry if im responding angry but a server needs to have at least a decent launch or connection without the coresponding lags and really i dont even see my damn inv as aim let alone that i can do something in the game ....... thats my problem so pls ......... as that i play with other players thy even say the game slacks something but i geuss u guys wil figure that out on your own
