I am not religious any longer but my sister is very religious and kind. When we were younger and my grandparents and parents would scold me for my stammering she would tell me that the greatest of all prophets, the one to whom God had entrusted the task of speaking on behalf of the Jewish people to lead them from Egypt, was Moses and that Moses himself had also had a speech impediment. Moses had feared greatly to speak, he had even asked to be excused from the task set to him by God due to his heaviness of mouth and of tongue. He who was ignored by others due to the laborious nature of his speech was still the one chosen for the task. When he set to it, he did indeed lead the Jews from Egypt. Likewise, perhaps now I fear to speak and perhaps now I will suffer for it but, she would reassure me, that there is time yet and that there is reason for such things. Furthermore, there are many before us who have questioned why Moses was made to suffer a speech impediment - these views are very reassuring if you have still any religious sentiment in your heart. I recommend this article on the matter: https://www.chabad.org/parshah/article_cdo/aid/1093373/jewish/Why-Did-G-d-Make-Moses-Stutter.htm I think it is natural to wonder why we suffer from an ailment and to feel anger about it. I really feel for your frustrations (I share them). I think it is not so easy to reconcile yourself to your impediment as just hearing one positive example. I wish you well.
