Trevor47 Thank you for your very honest and open post about yourself. You seem a very lovely man, sensitive and caring. Please do not worry what people post about your writing style. As long as you get your point across in your own way, then praise yourself for sharing yourself with others. Your posts are literate and easy to understand, however you type them up. You are taking time out of your day to interact with us and that can only be good.
Please try to put what your sister said about you where it belongs, in the past. As I child my nickname was terrible. I am called Jackie and words rhyming with Jackie, now considered racist were thrown at me all the time. Children, whether friends or relatives will do this with other children but hopefully nothing bad was meant by it. I don't take it to heart now anyway and neither should you. I know it is hard to put these things behind you and it soon comes back if someone criticizes you now, but they don't know what you went through then so they really are not saying it to hurt you.
I too have confidence issues, feeling like when I talk to someone that I am making a fool of myself at times, but what would the alternative be? Sitting in my living room all the time on my own? I'm not willing to shut myself away like that. The worst that could happen is that when I get home I think that I feel a little stupid for showing myself up or saying the wrong thing to someone. Maybe I won't see that person ever again, so it really doesn't matter. Or if I do, I could try to explain that I felt nervous on our initial meeting and that subsequent meetings go better. Besides, if you try to keep making a go at conversations, it does become easier. I talk to anyone and everyone and if someone doesn't talk back, then I politely excuse myself and move onto someone else. I have to do this as I go places on my own and if I didn't chat to people I would return back home not having spoke to a soul. And that is not good for the soul.
Lastly, on your original post, is big beautiful? Maybe not, maybe so. I think it depends on personality too. I think I suffer from reverse body dysmorphia. I think, even though I'm a size 20, that I look like a size 12 when I get dressed to go out anywhere. I have had two open heart operations since birth, I've just turned 50 and yes, I could do with losing weight. But I'm here, I've survived a bad condition and I am not going to start ripping myself apart because there are a few inches which have added on over the years. Take me as I am or not take me at all, that's my motto now. If and when I decide to lose some weight I will do. Too much time, energy and money is spent on people trying to make themselves look slimmer, youthful, happier, trendier etc. Botox, gyms, diets, all making other people rich. If we all just left alone then we would all be the same, like they were in my grandma's generation. She was beautiful in my eyes, small, round, white hair and twinkling eyes. She said she could eat me on a toasted butty. Now that was my beautiful grandma.
