You seem to be in a Toxic work situation and you may want to consider changing jobs. Seek a work enviornment with fewer co-workers with smarter people and a slower pace. You may also may want to move to a smaller city or town, or try public transportation.

This situation is making you more "Jaded". It is time for you to exit the situation.

The intentional excluding and ignoring you is a simple-minded mean spirited tactic that is offten used by people who are not very smart. They may even be jelious of you. Best thing to do is leave those people behind, and get on with your occupation and life.

Quit drinking and the drugs as well. Seek professional help for that if you can.
