@anime hey girl!!! getting depressed is actually not bad. So, try not taking it in a negative way. First try to understand the source or sources of your depression. Giving up is easy but that will never make you strong and you will lose the fighting spirit as your morale will come down. Being depressed means you are still fighting and haven't given up yet. You are just lost in the whirlpool thoughts and problems. Try to find ways and means to solve and eliminate the sources of your depression. Don't try all at once. Go one by one. Take advice from anyone you think is experienced or mature enough. Taking and opening up to people with your problems just not only gives you a space to think from multiple ways with people's ideas but also gives you encouragement and a sense of confidence. People will always try to help you and motivate you.
And try to engage yourself with hobbies and stuffs you like doing. It too helps. Thinking over and over about something just will give you unnecessary stress.
And about deleting your account. That won't be necessary. Take a small break if you want.
