This is my personal opinion. I think it doesn't have to be a short term fix. If you are curious enough and open minded you can find a long term relationship with God that doesn't contradict verifiable truth as long as you are willing to question collectively accepted "truths". For me, Natural theology has been one of the main foundations in my path to get closer to God. Understanding that physics stumbled upon the Spirit of God (the aether / zero point energy) and decided to look away has been super important in this journey. If you look at the recent work from physicist Nassim Haramein you'll see that Creation was not an event in a remote past after which God retired to his throne (Haramein doesn't mention God, but he explains how zero point energy sustains all matter at all times). If you agree that there is a Creator entity and you approve Haramein's theory, then zero point energy is the active force by which the Creator operates, and then creation is happening everywhere, always, and the same force that created everything is actively sustaining everything, everywhere, forever.
I would NOT recommend dating apps, you will most likely not find a real connection there and given the circumstances it might give you anxiety you don't need. I have had a similar path and situation lately and some things that have helped me are group activities like playing sports (I play soccer), group gym activities (I attend a strength and conditioning class) and most recently Bible study (I became friends with a Christian group of my area and attend their meetings now). Developing a relationship with God has been a huge upgrade for my life which is hard to put into words, but we also need human contact, and I was praying for that for me last night and this morning before reading this. I will also pray for you to find someone with whom you can share your life forever and never be alone again. If I could only recommend one thing I would say start with exercise, preferably a group. You'd be amazed by how much it can help to cope with loneliness and how much it helps to improve mental health in general. God bless you.
