Answer:
Okay I don't personally know you so I will give you rather broad examples.
My family has influenced me by always giving me a place where I feel safe, a support system I know I will always have with me, and important relationships which I plan on keeping forever, this helps me with relationships apart from my family.
My school has taught me everything I know thus far. With knowledge comes success. It gives me a place to be social.
My friends/peer groups have supported me through many hardships in my life. I know I can count on them for their support and acceptance. They make me feel like I have a place to belong, which is what everyone deserves. They have taught me the way I should be treated, and to never settle for less than that from anyone.
Social media, in particular, can positively and negatively influence your life. For me I use it to make friends with people who I would never meet in real life. This gives me a sense of being social and making new friends. Social media has also negatively influenced me in the sense that people can be harsh, and that damages your self confidence sometimes.
I really hope this is what you meant, and that it helps you/anyone else. I wrote this all myself so anyone can use it :)
