So basically, I have not been able to open minecraft in three months.

Minecraft isn't opening. I'll get to the launcher and I'll press play and my game will crash. I've tried a number of things such as, logging out, changing my profile, and changing the settings of my game. I've looked on the internet but a bunch of ways to fix it require the game actually opening. I've done it once because before I wasn't even able to open the game I could get to the server list then once I'd open a server it'd crash. I'm more then upset, this is my favorite game and I cant play it, in my opinion that's pretty bad, I really wish I could play but all I'm left to do it make a bunch of skins for a game Ill never be able to play unless someone can please help me!
