Covid is a nightmare - sorry it has affected your life and work plans so badly. I hate this situation so much and I am not sure the impact on people and the economy is worth it in the long term. I hope this lockdown and situation will improve, and then hopefully you can get a bit of your life back.
Re dating and illness...I know that when I am really depressed I feel so lonely, and it also affects my social life and all my relationships. I wasn't well enough to date. I wasn't well enough to socialise. My illness led to me also being bullied and being dropped by some of my oldest friends. I just started dating again, because I have been feeling somewhat better thanks to some treatments (see my posts in this Recovery section for my personal top tips on treatments that have helped me).
It's been about 3 weeks, so early days, but am getting out while I can walk down the street (I was bedridden for a year with depression). BUT as for finding love. I had my heart broken by the first man I dated who ghosted me - and I knew him from real life Then I got on Tinder and also Feeld (I personally prefer Feeld, as while it is maybe more for hook ups, I find it more respectful).
I have met several people, but while I have met two people I liked, one of them was really rude and arrogant and crude - he sent me unsolicited crotch shots after our first date (where we'd only kissed), and he wouldn't discuss how stressful I found that...(especially considering he was richer than me and arrogant) and so that ended, which was disappointing, but I'm over it now. The other one I like is younger than me and it's more of a friendship than a love relationship. He's awesome. I'm really glad I met him - but he is 13 years younger than me and from a different background, but interesting and fun.
I do recommend dating younger people as something that can be healing but also not make you too vulnerable. I almost avoid catching feelings for people if possible. If they come to me, I won't resist them, but I am actually quite pleased to not be feelign big feelings atm.
I'd recommend feeling a bit better before dating, because otherwise you will be vulnerable. I was vulnerable to the guy I fell in love with who was mean to me and ghosted me. I'd known him a long time. But I don't regret risking dating him and at least I am over him now. It wasn't a long thing, and he is a w**ker!
I don't think any of us can force love to happen...and for me, I tend to fall in love with the wrong people, so right now dating people I like and who like me is my healthiest option.
I like the options some of the others have suggested, about online meet up groups and hobbies. Maybe with a mutual hobby you will meet some nice people. Religious communities (if you can stomach religion) can also be good ways to meet people. A lot of them are online and have other people also online, that you can meet. I have also thought about online mental health support groups. I am only in the past two years considering myself as disabled (though I always have been), and it is a step to join such a group, as I feel somewhat vulnerable and a bit ashamed, but I am less ashamed than I was - as these are illnesses and not our fault. So being in groups with others who understand could be good. If you are in the UK, try calling the Mind helpline. I called them the other day, they will ask you what Borough you are in. Other local mental health groups - some of them must hopefully be online.
My ex with Bipolar has been in and out of hospital. Every time he comes out he has to rebuild his life again - and he does. So kudos to him. I have not always wanted to rebuild my life, as I have been so ill, but feeling better even for three weeks, I'm gonna rebuild while I can. Other people left my life, but he was a great support. So perhaps peopel that understand, for example other people with Bulimia, could be good friends for you.
Not the same illness...But by the way, I just read that journalist Hadley Freedman is about to publish/write a memoir about her battle with Anorexia. That kind of memoir could be helpful? She is writing in the hope to give hope to people.

I hope this long rant has useful things in for you. What I really want to say is sorry you are feeling so lonely and especially after all your trauma. I hoep you find that people here care about you and are here for you, and I also hope you find more good people in your life. I have actually found that my illness has got rid of the people who weren't good in my life, and I am lucky to be left with the good ones. If you don't have the good ones yet, they are out there and you can find them. Just stay safe and trust yourself, and keep looking. And when you don't find them, keep looking. They are out there.
