Prayer Requests - Anxiety and extreme sadness

I’m 20 years old.
I started struggling with anxiety and extreme sadness a few years ago caused by the extreme guilt I felt from certain sins I had committed. My suffering lasted for many weeks. Unfortunately, now it’s been a couple times where I feel anxious and extreme sadness for no reason at all. Nothing tragic or bad has happened to me. I simply suffer with no reason causing it. I’m constantly looking for comfort and peace, relief from my suffering. I cry and feel hopeless. I don’t know what to do. I get this horrible feeling in my chest and I feel restless and just horrible. I just end up fighting to get through the day and then the suffering starts all over the next day. I’ve been going to daily mass and I go to confession every month. I’ve begun praying the rosary daily again. Thankfully my parents are very supportive and have already given me advice to pray and ask God to heal me. Regardless, I’m still looking for an immediate source of comfort and peace. I dread the future and having to leave the house. I’ve talked to many other people to try to find something to make me feel better. I guess I just have to wait for time to pass and for this suffering to go away on it’s own.
Please pray for me.
