I just turned 50, so does that make me old? hehe
the question would be what are you hoping to get out of a relationship? are you hoping it will make you a happier person? to have a healthy relationship, you have to go into it healthy with a healthy partner, otherwise you are just going to have more dysfunction and life will be more challenging and miserable. and who wants that?
I don't think things like a job and clothes are barriers to a good relationship. lots of people can look past that. even a low sex drive can be worked thru. but social anxiety and depression can put strain on a relationship.
Take time to work on you and get yourself in a really good place independently. Find your happiness and the relationship will follow.
