How do I develop a thicker skin and not let people get to me?

I am 35. I get sick of being harassed at work about my personal life...about why I’m not married with kids and people constantly suspect that I am gay (actually I am bi). People constantly tell me I need to hurry up and get a girlfriend or wife and have kids. Whenever I bring in food that I cooked to work, people tell me I need to get a wife so I don’t have to cook my own meals or people will make jealous comments about how my meals look (even if it something simple like chicken and rice) .
Also people, especially young people in their early twenties, that I work with will make fun of how I talk or sometimes they will give me **** about keeping to myself. There is one kid that always talks **** about me when I’m sitting across the room where I can barely hear him and people will look over at me and start laughing but when I ask the kid what exactly he said he just laughs or walks away. When dealing with other people I ask a legit question and get a sarcastic response it really hurts my feelings. I have never been able to handle sarcasm without getting upset because I never know how best to respond to it.
I had a situation a couple weeks ago where a girl tried to start **** with me in front of one of my bosses by claiming that I bumped into her when I walked by but I was no where near her. She threatened to do something to me if I ever bumped into her again. I got so ****** at her but didn’t raise my voice and I told her , “Lose your ****in attitude. I don’t have to take **** off you.â€
These kind of incidents at work get under my skin so bad that I spend my time off angry as **** that I have to go back to work and I am constantly on edge because every time I am nice to someone, at work or anywhere else, they try to walk all over me. I have so much anger that I hate people and spend time thinking about how I can really do harm and get revenge on people in gruesome ways.

Here's what you say...

"If you ain't paying my bills or riding my ****; put up or shut the **** up"

Sorry sis, didn't get in before your stalker. 😫

What was the point of his comment anyway?

Pure $hithead factor 😋
