It's important to recognize and deal with why you are the way you are IF you have access to a therapist who can help you with this.

But you don't seem to have help readily available. I'm not a pro anything. And my parents did a fair amount of damage to me, too. However, that doesn't define who I am. The things I mess up on or can't do, might be due to them, but does that matter now? Not to me it doesn't. That knowledge doesn't give me a reason or an excuse to work on myself , by myself, when I am able.

You seem to be pointing the finger at them for everything. But what does that accomplish?

I tend to call it like I see it and yes, your parents ****ed up. But you can't go back and change that. What you have to do is make decisions for yourself.

Life is a series of choices. Sometimes you pick one and it's the right one. Sometimes you pick one and it's that waaaaay suckyest one. But we pick ourselves up and try again, with our next choice.

You seem to know it's wrong to stay in bed all day. Now you know it's wrong, what can you do about that?
You seem to know it's unhealthy to be online all day. What can you do about that?
You seem to know that it would be better at your grandmothers. What will you do about that?

What can you do now, to improve your situation? Do you want to do it?
