I hate these threads because someone will always trot out the old Roald Dahl quote, and a hundred other posters will rush to tell the OP that they've never seen an ugly person.
Absolutely the word ugly is unpleasant in it's connotations, but that's where the OP is coming from, the world is not kind to people who are less than average looking, and some people are. It's just a fact, not a judgement call, or that the poster has issues that need intervention.
People treat unattractive people less favourably than they treat attractive people. Teenagers can be especially cruel, often because of their insecurities, but the outcome is still the same, conventially unattractive people are an easy target and unless a person is exceptionally secure or has other shining qualities, it can be very difficult.
So spare OP your homilies.
@YesItIsTrue, I understand what you're saying. And actually I do think it might be worth working through with a therapist, because it will allow you to get to the bottom of the question, and more clearly see the answer, which essentially is, 'I am scared that my potential child will have to suffer what I did, can I give them a secure enough base so that they can cope with the abuse/bullying that I did/do'.
I'm not going to tell you that you're worthy, you've asked the question, you obviously care about a potential future child. A strong base is what children need really, and asking the difficult questions of ourselves is often what provides that.
