Freezes and kicks me out when i get on minecraft.

This has been going on for a couple weeks now. It's very irritating. I played with my dad and uncle once and it worked just fine but after that it totally went downhill from there. When I go to the title page it'll play the music and the background will move for about a couple minutes till it freezes for another couple minutes then kicks me out. I even tried to let it load for a bit and tried to quickly join one of my worlds I've made but it'll still freeze on me and kick me out. Tried to uninstall it and re-download as I seen most people said to do but that didn't work and I tried to delete all my saved data as that also didn't work. Please someone help me out this is really annoying as I would really like to play Minecraft again.
