Regarding the loneliness problem, that isn't as intractible as I used to think it was for us Venusians. In my case it was largely an issue of getting my emotional algorithms right, which requires effort that isn't quite intellectual effort - but intellectual capacity certainly helps understand what the new version should look like.
If you're interested in solving this problem for yourself I would recommend the book 'models' by Mark Manson, reading it made a world of difference for me.
I know I can work on my social skills. The compounding factor that ruins my chances is that I also am not physically attractive. So I get very few chances to practice my social skills.
This whole getting few chances in the first place is what is making me unhappy and making me feel lonely.
And before you ask, I do put a lot of effort into meeting new people.
Thanks for the book suggestion, anyway.
What makes you think it's because you're unattractive? Even so, you can achieve a lot with 3 months of strength training at the gym. (hell, you'll see results in the first couple of weeks)
Consider that the vast majority of people don't even do that much - It doesn't take much to be above average.
What have you done to stop being unattractive? Unlike the common copes I think attractiveness is one of the most important attributes for a person in determining how the world treats them. Depending on how much money you have there are a lot of options for changing it
