Do you think therapy actually helps you at all? My personal experience with therapy is that it's not useful for helping with dating and social struggles. Most therapists don't have the kind of lived experience we do to understand what the struggles are or how painful the loneliness is. The psychology industry works under the false assumption that all depression is caused by deficient serotonin production, where I'd argue that in cases like ours, it's actually our oxytocin that is deficient.
Most people get to experience having someone to cuddle, kiss, have sex with and all the rest of it. They're getting their oxytocin needs taken care of, so they take it for granted. They can't imagine what it would be like to go without that for several years, or perhaps, forever.
If you're anything like me, your issues are social as well as emotional. You weren't able to develop the social and dating skills necessary to have dating success, which is the real reason you can't even get a coffee date. On top of that, years of struggling with loneliness have probably dulled your ability to enjoy anything and everything (anhedonia), which further makes it difficult to relate to other people and negatively affects your motivation to do things.
I don't think your situation or mine are completely hopeless, but you will need to invest in learning the social and dating skills you're currently lacking. I can recommend a dating coach who I've kept my eye on and believe in, but you'll probably need to save up some money before you'll be able to afford to invest in their program. They teach frameworks about getting dates, reliant mainly on cold approach. Their content is good. Here's a link to their free YouTube content

Another thing I'd recommend is seeing a cuddle therapist instead of your regular therapist (if you can't see any benefits from your regular therapist). A cuddle therapist will give you the physical intimacy you need to increase your oxytocin production whilst also being a confidant who you can talk about your struggles with. I just recently started seeing my cuddle therapist again and have found it more helpful than I ever found seeing psychologists.
Another post you've made talks about your past determining your future. It doesn't have to, but it likely will unless you make the right changes. I'm someone who knows what you're going through more than most, so I hope that lends more credibility to my advice.
