What do I do?

So I have just 3 questions. One of which for you.
1. I have been having problems lately involving random waves of depression, I want to go to sleep all the time but my body refuses to go back to sleep until I am too tired to even stay awake. I have attempted to cut out electronics before bed but will end up getting bored after lying still for 2 or more hours. I feel unmotivated to do anything and I'm losing hunger. I settle for a breakfast burrito and a cup of coffee, and whatever my mom makes for dinner. When we have leftovers I just end up not eating anything for dinner. It's not like I have been snacking either, I'm starting to lose a lot of weight. My sister is saying that it's just due to the season change, but I have never had this happen since I had my friend group but they won't message me back when I need someone to talk too. What should I do? I am 98% sure that it's most likely my waves of depression, but if you have any other ideas please tell me.
2. I have a problem where if someone expects my next action due to what they know about me I stop and I don't do what they wanted me to do unless I have to follow what they say such as my parents telling me to do something. Some examples are if I'm doing some art and someone asks me where I got my inspiration I lose all motivation to continue and I somehow lose my ability to draw. If I like a certain thing and my family starts to base all my actions off of it, I dislike it. I can't even watch anime anymore because everything that was said or done to me because I watched anime makes me dislike it. Is this normal? I don't even know what's wrong with me anymore. Do you also experience this?
