How can I get rid of this feelings?

Creative outlets that involve people other than your family might be a start. Music lessons, a ceramics class, a book discussion club – those sorts of activities. You'll get feedback from people who don't know you and you may even discover aspects of your personality that you haven't expressed before. Try to dismiss the negative messages your situation has programed your mind to generate.

In my personal experience, depression seems to come from boredom. Try to find something interesting to do. Especially if that interesting involves physical activity.

I won't be able to because I have an old fashion Mom that won't let me go anywhere, and I got my depression from when my friend passed away on January 10, 2022 by a police car.

Is there anything your mom will let you get involved in? Are you involved in a church at all for example? Maybe you could volunteer there and help out with the younger kids....is there a youth group? Many towns in the summer have community programs for kids; would you be able to participate in those?

When you get back to school in the fall, look to get involved and also since you have unresolved issues with a friend's death reach out to a counselor to help you deal with your feelings. If your mom is not in a position to help you get a counselor or therapist or unwilling to, when you get back to school you can reach out to see what they have available. Most schools have an adjustment or similar for children that are going through a rough time.

There are many things you can do at home to interest yourself. You can draw/ paint, knit /crochet, cook/bake, learn to play an instrument /sing, write a children's book, do the crosswords or learn how to develop one, redesign your bedroom, learn to sew, jigsaw puzzles... and tons of other crafts you can do in one room.

As for the depression itself, I am of no use to you.

Best of luck, and keep us posted. Also, you don't say how old you are or where you're at in your life. Are you still in high school? University or college? Are you working and, if so, at what?
