Is it impossible to resolve long-term depression/anxiety without

Yes, but I think its more efficient and easier with the help of a professional.

Yeah, i manaaged it, but it really does mean you have to do the things you really don't like to do. You have to go out more, you have to try make friends, you have to try improve your career or education, you have to take up a satisfying hobby, you have to clean your room, you have to work out. These things suck to do but make you feel a million times better if you keep it up, and it becomes easier to keep up after a while.

Oops, I read OP as "is it possible"

It's time consuming and exhausting, but may be possible if you work for it.
You'll have to go through many ups and downs, get used to them, face them, accept them, change yourself, your thoughts, accept your thoughts, find what matters in your life, find energy to pursue things that matter; all this while still sometimes feeling like you're drowning and sometimes being rather okay.
You'll go through hundreds of realizations such as "it seems the more time I have to think, the worse it gets". You'll notice it, question it, forget it, remember it again, implement it in your life, find it works for some time, then it's not working and you have to find another thing that works, you'll try to avoid thinking completely, but you'll realize it makes you feel like shit in the long run and you'll feel as if you never moved an inch, which will be completely untrue.

Outside help is helpful to speed up all of this, to be supported when you're down, to give you focus when you can change, to give you structure for peace of mind.

You can also try self-help books if you can stomach them. Sometimes they give you good ideas or another perspective.

what would be the benefits of doing it without help? in some cases it is probably possible but it depends on many things.

meditation , exercise and years of self help books and YouTube videos worked for me

Eight years here

Tried books, exercise, music, medication, various sports and hobbies, a ton of drugs, self-improvement

I'm not sure, but I think I feel even worse now. Trying all those things ensured me that I was born broken and nothing will help.

Depends

depression is either self-perpetuated with a lot of negative mindstates or an actual chemical imbalance.

Which one is it?
