How do I get through the waiting phase?

I'm F and in my mid 20s. And my biggest wish is to be in a relationship. But in order to be 'accepted' in the dating pool, I would need to 'fix' myself first. I've been struggeling with mental health issues (depression, anxiety, loneliness, insecurity about my looks) for a veryy long time and obviously no man wants a depressed gf. So I need to work on my anxiety and stop being insecure/shy/introverted first. I also need to do some work on my body as I've lost a lot of weight and would want to do the lose skin surgery to have a more toned boy, but I need to save money first as those surgerys are expensiveee but saving needs time as well. Overall this whole self improvement journey would take (as I would guess) 5 years minimum. So my question is, it would take lots of time until I 'fix' myself but my desire to be in a relationship is very huge right now. How do I endure this waiting phase? I try to distract myself and keep my mind occupied but the desire is still there.
