You seem depressed. I do not know if it is temporary experience or more of a chronic depression. You did say that you have been depressed since you were about 10 years old and this may indicate more of a chronic-type depression, such as dysthymia. You may also be experiencing a general unhappiness with life, and not necessarily depression per se. It is difficult to tell from your short letter.
You said that people do not like you. This is your impression but the fact is that you do not know this to be true. Unless you surveyed these people about their opinions of you, you do not know this to be a fact. You could very easily be misjudging these situations. It is also possible that you are judging these relationships correctly but you’re trying to befriend the wrong people. Both of these circumstances are possible, therefore it’s best not to jump to the conclusion that it’s “you” that is the problem.
You take this same sort of self-blaming tone and attitude regarding your inability to find a job. Maybe you have not yet found the right employer or perhaps you are sending off a negative or depressive “vibe” to possible employers and that might be why you’re not able to find employment.
You said that your parents are “bad people.” I am not sure what you meant by that expression but I am taking it to mean that they are not people you can or could have gone to for support or advice. You mentioned that your mother has her own set of problems and she may not be emotionally available to deal with your issues.
It might be helpful for you to consider therapy. You said that you have few people to go to for advice. A therapist can help you objectively judge whether you need to alter the way in which you behave in situations regarding employment and relationships as well as help you with your depression. He or she can evaluate very thoroughly the way in which you interact with others and coach you on how to modify your behavior if it is deemed necessary. A good therapist can help you immensely with all of the issues that you’ve mentioned. I hope you will consider this advice. Thanks for writing. Take care.
