Someone help I’m afraid my life is sinful

I (21M) struggle as we all do and there’s is no shortage especially on this sub about you g men like myself who struggle with the flesh and not touching said flesh to keep my wording family friendly, and that I can’t stop myself from seeking out certain media outlets that councide with the struggles of the flesh creating sinful actions (I know I’m talking slightly flowery but I don’t want to use rude or crude wording) besides my internal struggle of the lust on flesh I also struggle with the anxiety of death and it finality anytime I think about it I get extremely anxious and feel like I have to puke and breath really hard the though that one day I will shrug off this mortal coil not knowing wether I did enough or not enough is hard on my mind even greater is my wavering faith because when I picture death uts just the void though I use faith to bring myself out of my panic attack reasoning that there has to be something after death there must be

Then there’s the struggle of following God’s will but one in particular, God in his love wants us to love one another and to procreate and fill his world with children, as said in Genesis procreation is the greatest and most selfless live as two flesh become one flesh and the one flesh becomes two ie two must come together as one (marriage I take that verse as) then they come together once more and create new flesh (a child) not to mention all of God’s iconography in the Bible of asking his disciples and important people to go forth and let their seed be as many as the sands and stars in the sky, all this to say I’m afraid of being alone that I will never get to see God’s joy of creation though getting married and having a child and this is my second anxiety that I am not enough for anyone

I became a Christian because I had a night of lust and struggle of flesh with a woman but when all was said and done I felt empty as if I had done something wrong, I felt guilty against myself and I turned to God knowing I had sinned by breaking the sun of lust and sex outside of marriage and I have begged my forgiveness on that sin

But I also trust in God because I have been given so many opportunities lately, I’m on my way to a small promotion at my job and i thank the Lord for opening my ears and my mouth to ask how I could be better and that was answered by my boss telling me if I wanted to be better to take the steps to get a lower leadership position and I’m waiting on that, I thank the Lord for this gift and only hope that God in his infinite forgiveness for he who hasn’t given his only begotten son to the world, who died upon the cross for our sins that as I proclaim the name Jesus Christ as my Savior that the above can be cleaned and my heart be steeled in his name

However if anyone can give me their due diligence and opinions on help with my anxieties and struggles that would help me on my path
