Right now a good portion of the people who work at my job hate meand make fun of me behind my back. Part of it is because I'm not too great at my job and also because I'm simply not good at talking to people does anyone have any advice?

Some details would help us in arriving at solutions tailored for.
Job title? Duties? How long have you worked at your current place of employment?
Also, I consider hate to be a strong word. Do they know you well enough to dislike you so much? Are they worth the effort of you changing their opinion of you? What are your thoughts/opinions on them?

These are just some starting points.

Office politics... Adding on to what >>2 has said, how do you know the reason they're talking behind your back? Do your colleagues constantly talk bad about you? A good way to start conversations with them is to ask them about work related stuff. You mentioned that you're not too proficient at what you do, you could seek help from them when needed.

Ultimately there must be some kind of strong distaste for you to be continually be the talk of the town. Try to close up any misunderstandings by talking to them.
