No one is an "awful" person just for not having supports. People stop communicating with family for many reasons. Some are valid and some are not. You have to first identify why you feel they are judging you. What situations bring this feeling to fruition. Is there a particular reason for this or is it an overall statement. Sometimes we feel certain things and they are simply our perceptions. Decide why you feel judged and if through a better relationship these feelings can be resolved. You shouldn't have any relationship that is toxic to your well being. If the relationships are not healthy ones then you have every right to keep your distance.
If the relationships could be healthy then ask yourself who you want to respond to and why. You may choose to be in contact and reunite with some members and not others. Choose only what is healthy for you and seek out those relationships. You are free to ask certain members to be part of your life without allowing negativity.
If you genuinely feel they are judging you then you may be legitimate in not having a relationship. Only you can decide what you need and what you want. Don't be in any relationship out of obligation. It should be beneficial and positive. If you choose to distance yourself then do no apologize to anyone for your choices.
