First of all, english is not my native language and on top of that i'm iliterate in my own native language, so please excuse me for my bad english.

I'm severely mentaly ill: mildly autistic but severely traumatized. My father was a drug addict, my mother is kinda sociopathic and my family is from the communist elite here in my country. I was basicaly expeled from my family for trying to become catholic. I'm completely isolated; no friends and family support at all. I'm becoming homeless pretty soon. I'm living in a socialistic country in wich churches are taken over by anticatholic priests (people related to a catholic church bomb attack who killed almost 100 brothers, 40 of them were children, just to give an example). I was baptized in a mass that was probably sacrilegious (I don't even know if my baptism was valid). I have so many mortal sins that I don't even know how to perform a confession because I can't keep track of my sins and the brain fog is overwhelming. I feel paralized not knowing what to do next and I feel like i'm going to die soon. I just want to try to get my act together, but i'm too confused and lost.

If you don't know how to make a confessio, just tell the priest you don't know. He will know how to help you. Don't worry if you can't keep track of your sins. Just tell the priest that. That is the work of the priest to help you in this.

The priest is there to hear your confession but it is really Jesus you are confessing to and Jesus reads hearts. So be at peace.

Yes, as long as you do the best you can trying to remember your sins, if you forget some, you can always say them in your next Confession, after you remember.  As long as you're sincere and not deliberately trying to hide any sins, all your sins are forgiven.  So don't let that prevent you from going to Confession.

In which country do you live?

What country are you in? Is there anyway you can leave and go d a community who couldcould help you?

I think Sri Lanka, I remember hearing about the attack he mentioned in the news.
