What if my dad likes telling jokes?

Don't be discouraged, children from divorced families will be like this. You say you don't talk to your workmates, and your interpersonal relationship is not very good, but think about it. You don't communicate with people, and they don't know how you get along with you and how you like you. Don't be so inferior and look down on yourself. You said you looked down on yourself. Who else likes you? It is irresponsible of parents to divorce. Don't blame them. They have their own lives. Now that you are working, you should learn to be self-reliant and try to make yourself better. Lack of ability and education is not the reason. No one is born with many things. I learned a little. A little setback can crush you. Then your life has really failed. Throw away your inferiority complex. You don't need it. Be yourself happily. Only when you are cheerful and have communication with her will everyone like you.
