Depression or just phone addiction?

I hope this is the correct subreddit. I'm sorry if it isnt. I use my phone a lot. I end up wasting a lot of time on insta or YouTube. Some things I've noticed about myself: •Lack of motivation to do anything. •If at all I do anything, I take constant breaks and end up on my phone. •Sometimes, If in a day I sleep for 8 hours, then I've easily used my phone for around 16 hours. •I spend like 95% of my day in my room. •My social battery(if that's a thing) dies after 1-1½ hours. •Couple of years back I could remember the details of conversations I've had with people for months/years. Now I can barely remember the details of a conversation I've had last week. •I skip meals. I feel hungry but don't want to eat. If I do it take a long time for me to finish eating. •I get angry/irritated very fast. •i procrastinate big time.

I don't always feel sad. Although I have had suicidal thoughts a couple of times(not very often). I run away from my emotions and use my phone. My phone basically acts like a buffer. Just wondering I'm depressed or if my phone is just affections other activities of my life. Thank you for reading if you reached this far.
