I feel that way often. For me it is not anything they do or say, it is what I have heard in my childhood about my mother being from the wrong side of the tracks from my fathers family. My father's family was quite wealthy, my mother's family was very poor and criminal ( tho my mother was never a criminal). My father was an alcoholic and we were probably lower middleclass, tho most of our money went to my father's addiction. He was also abusive and it was just a very dysfunctional upbringing.

When my parents divorced my father's family and my father left my sister and I in the past, zero contact. My mother left me homeless as a youth and I struggled very hard to find any normalicy. I am now a divorced mother of three who fled from my abusive husband, even tho I managed to get through college I am on disability. I have a bf of 7 years who comes from a good loving home who are well off as well and excepted my children and I with open arms. Even tho I have worked very hard to get where I am I continue to feel that I am from the wrong side of the tracks and do not really fit in. Like an imposter almost. Most of the people I know are middle or upper class, and I do find it hard to feel comfortable and as tho I do fit where I am.

That said, I am a loving person, I do what I can to help others, I value people over things. I work very hard part time at a low paying job as a maid for extra money to help give my kids a better life. I know that I do my best as a mom, a girlfriend, daughter, sister and friend. My children are really great and heartful young people, I must not be failing at everything even tho It feels I am sometimes.

So maybe if you feel anything like me, the feelings as far as I can see come from within. I often compare myself to others in middleclass and feel disappointed with myself for where I am at which is poor really. I often forget the challenges and barriers I had to overcome to even get to where I am now. We were not all born on equal playing ground either. I've been trying to work on appreciating where I am, and acknowledging that I have worked hard, my life may look different than others, but I also have other successes that are unique to my situation, and they still have value.

I don't know if any of that helps you, but I understand the feeling of not fitting in there or anywhere really. This is something I have been working on for the last year or so, I don't want to feel like an imposter my whole life, and no one is going to tell me to turn in my pearls, I just need to realize that maybe there is no real dividing line.
