Basically I'm actually quite comfortable with myself as I'm fine with who I am as I don't really care about what other people think about me. As long as I do things at my own pace and I do not force myself to do something that I cannot accomplish, I'm really fine with myself. I don't find a reason not to be comfortable with myself as I feel that it will only bring harm to myself.
Moving on, how do I ensure that I do not hurt myself? Well, I basically just do not force myself to anything that I cannot do by myself or over stress myself. In the event that I do feel stressed and depressed, I will talk to someone I trust so that I can share my troubles with them. After all sharing your woes is better than keeping them to yourself.
