Nowhere in the bible does it say a person who commit suicide is not allowed a proper burial. In fact it does not even say suicide is a sin, but be warned, you could be reborn into an even worser life if you take your own life. One where you do not even have internet.
If you are thinking of committing suicide first try a help group like Samaritans: https://www.samaritans.org/how-we-can-help/contact-samaritan/ or yet, the none free therapist at Better Help: https://www.betterhelp.com/get-started/. Please do not give up, most suicidal thoughts pass in as little as a week or maximum a few years. Think of how much life you have left in ya.
For you to own a mobile phone or computer or have a library to access this website means you are better off than some. Think about what you have and could lose. Seek professional advice. You causing others grief over the loss of you could mean you will get it back done unto you.
Love the trinity so that they may ease your problems. Pray and you will be heard. Do not risk suicide and the next life you are thrown in hell due to being different about how you feel about God (hating him next time, for example).
