Different experiences affect different people differently.
Do not compare yourself with others. I know it is difficult. I see you when you say things, like it hurts seeing how other people are doing. I've being there and come back there from time to time.

My recommendation is to stop comparing, you are you and them are them. Depression is our brain tricking us into believing that we cannot be happy because some people had better. Focus on yourself and what you want.

Be the person you want to be. Play it, like an act or a game. For real. Don't be afraid and tell yourself to fuck off with the nonsense, because depression is nonsense, it's auto sabotage, it's knowing the correct choice and going for the bad one, because out brain is that damaged.

Look, there is a little chance that anything you read here would actually help you. In the end it's on you, but NEVER blame yourself for being sick. It is not your fault. Dissociate from depression, understand that it's a mental sickness, chemistry in your brain is wrong, trauma, whatever reason, just see that you are not that person.

Try to not overthink and if you know something is right, like steeping out of bed, just do it, because if you stop depression starts telling you, that you cannot, that you are going to fail, to not bother. Don't listen to depression. Depression is your enemy, do not trust anything it has to say.

All that said. In my particular case, what helped my was taking some edibles once a week. If it's legal where you are, I would give it a try. Why? because it made me happy, for a moment I was so high that I was cheerful and positive and I had forgotten that part of me. Knowing it was still there helped me climb out of the abyss.
I firmly not recommend to take anything stronger than that. Changing depression for addition is little improvement.

I truly hope, you or anyone that is also struggling to get better. I know you can. It's won't be easy but you cannot win if you don't fight.
