God wants me to kill myself?

No God does not. Demons do. They are lying to you, infecting your thoughts, trying to separate you from God. Don't listen to them. Suicide is a sin. Anything which prompts you to destroy what God has given you is a lie, given to you by demons.

Pray these words:
HIDE ME IN YOUR WOUNDS, LORD JESUS

Let the Father separate what is good from what is evil, you are probably thinking you are worse than many successful individuals that are quite more dead than you already.
You are going to meet God anyway, and if you fold now you forfeit any possibility to do something good.

all it matters is the intention you do things with, the outcome does not depend on you a lot of times.
So if you do wrong things do less of them, and try to do things with a good intention. You have nothing to lose.

No. By giving up you will make certain that things will be bad, there's always the possibility that things will get better and improve. We all fell short from God, dont feel guilty.

since its on topic, if i do reckless activities (such as mountaneering or kayaking with cero knowledge) in the hopes of dying during the activity, does that count as suicide as well?

Other than doing even bigger sins because I'm retarded, Yeah.

You're not cursed, you're stuck in a bad place. God doesn't want you to be stuck in a bad place but if you commit suicide then you're certainly not getting out into a better one.

It counts as suicide if you do these things improperly. It's not "natural causes" unless you're actually trusting nature.

I myself have been close to death numerous times already yet I still can't do anything about it because I'm simply retarded/unlucky.

That's where you're wrong. Surrender yourself to Jesus and He will put His Spirit in you. You will experience more love and peace than you've ever experienced before, and you will have meaning in life. And through His Spirit, He will empower you to live holy. Put your trust in His promises, user.

Come unto me, all ye that labour and are heavy laden, and I will give you rest. Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. For my yoke is easy, and my burden is light.
- Matthew 11:28-30
