This is similar to what happened to me a couple of years ago. I signed up for a dating site because I felt lonely and instantly felt a lot of anxiety and wasn't sure I was ready as soon as I filled out my profile but stuck at it, I soon met a guy who completely took advantage of me. I was very naive and immature mentally, as well as very manic and he knew this and very quickly took advantage of it, he used me for sex and he was rebounding so used me to help himself move on too. That relationship was a disaster. We broke up and I was back on the site within two weeks which was a terrible idea, met another guy and sex happened with him very quickly. I was in a really bad place and both of those men messed me up for a while. I then met another guy on a dating site when I was depressed, and luckily he didn't take advantage and was very supportive and loving and I'm still with him now.

What I learnt from these experiences was that when I was manic, I was vulnerable and men could spot the vulnerability in me and used it to their advantage. Not all men are like this but a lot of men on dating sites are scumbags in my opinion. None of them seemed to be scared by my diagnosis, except one told me that he would leave if I relapsed and it became too difficult for him, a nice guy! It's totally your call what you decide to do, if you feel you're not ready maybe it's an idea not to put yourself in that situation. If you're still comparing people to your exes, maybe give yourself more time?
