Existential OCD/ (crisis?)

Hey everyone, this is my first post here and I just have to get stuff off my chest. It started so randomly and so recently. I (21 m) came to accept my morality and my death at a fairly young age following watching 'UP' and my grandfather passed away. But a youtube video talking about a character struggle with their death as part of a character arc, that one line made my mind fall into a rabbit hole on death, what is death, what's after death, what's life, it's meaning, is there a God, what am I doing with my life, what do I want to do? And is it worthwhile? I felt like I like was slowly disconnecting from reality and that nothing was worth it. My interest like guitar, combat sports, pro wrestling and video games didn't bring me comfort. I've even have trouble eating, just two bites of a chicken sandwich felt like 30 bites. I've just keep thinking about my life and my inevitable death and I couldn't focus on anything else. I think it's because I feel like I'm at a war with my mind, people say life is to short and at the same time to not rush it. I am a Christian and I do believe in an after life of peace but I question what's real and what's not and I don't ever feel happy. Is anyone else going through what I'm feel I really need help.

For the past week-ish I have been having a really scary existential crisis that feels like it is stemming from ocd. It started with me being freaking out that i’m going to die one day, then it merge into me being freaked out about what was going to happen after I die (mostly the thought of nothingness). I found some very brief relief in some spiritual beliefs and watching psychic medium readings but then I started think about even bigger and harder to answer questions such as, “if there is a God, who created God?”, “Is the afterlife scary?”, “Could the afterlife end one day?” “What is the point of anything at all?”, “Will the sun exploding destroy whatever afterlife exist?” Really ridiculous questions. I truly believe that there is something after death and something that exists as a life force science cannot explain, but the fact that my mind can’t comprehend or figure it out is really really scary. I feel as if I am going crazy. I have been thinking about nothing but the universe and the meaning behind it all and where it all came from. I can’t enjoy anything anymore. I just want to lay in bed all day and even that is hard. I have been non-stop watching videos about people’s beliefs about this topic trying desperately to find some sort of answer and I am starting to think that may be a compulsion. I am trying my best to remind myself that I when I die I will have all the answers to these questions and I don’t need to worry about this right now because it truly doesn’t affect anything or change anything in my life but it is really hard. I feel as if I have “uncovered” something and my life will never return to normal again. I am terrified that I am going to go crazy or start having hallucinations and that I’ve ruined my life by researching into something so complex and not understandable at all. Any kind of suggestions or anything would be helpful, I hate dealing with this and feeling so crazy and hopeless.

I really need help. I’m suffering from existential ocd and I want to hear experience from those who are suffering from the same thing. I don’t feel real. I dont feel like I’m really here and if I am I dont really see the point in doing anything if I’m just going to die. I hate this feeling of feeling like I shouldn’t do anything at all because I’m gonna die and it’s gonna be erased anyway. I hate this. I cant stand this and I should be grateful for my life because there others that will never experience it. But it’s becoming dreadful and I feel like I’m going crazy. I feel sick. This feels worst than my other themes. I hate it so much.
