Anxiety and dating

I just got out of an almost five year relationship a few months ago. I’ve started diving back into dating through an app just to see what is out there. But this has brought up some of my anxiety issues and abandonment issues. It’s not due to anyone in particular- just my brain doing it’s thing. Sometimes I feel like I won’t be good enough, that I can’t be myself around new people, that I’ve let myself go over the years, am I too old. I’ve talked with a few guys and have even gone out on a couple dates with one but then my fears/anxieties hold me back. I worry about why haven’t they text me back, when can I see him again, did I say something wrong? I have a lot in common with the one guys I’ve been out with which is nice because I usually date guys who seem to have opposite interests. I think the worst part is coming home to an empty house and trying to find something to do in the evening to keep my brain busy. I moved to a new town where I don’t know anybody so I don’t have any friends close to hang out with. This town is only 1300 people and the closest larger towns are at least 45 minutes away. I spent the weekend visiting with my best friend who lives five hours away but now that I’m home, I feel so alone. Then my mind wonders if I should even be dating anybody, if I should just work on myself and find ways to keep myself busy and happy. I started seeing a therapist shortly before my ex broke up with me but unfortunately due to my high deductible plan I can afford to do that any more (almost $500 out of pocket for two visits).
