Well, Tinder doesn’t has the best reputation. Not to shit on the users. Everyone I met through Tinder was super nice and I had a great time during those dates. But the App itself tries to drive you crazy and throw money at it. I don’t know where you’re from, but I’m sure there is a better alternative.
The best advice I can give is: Focus on yourself. Treat yourself good. Learn to love yourself. Then put yourself out there (maybe in one of those pesky bars?) and voilà! You start meeting new people. I cannot stress enough how attractive contentment can be. No one wants a sad lump.
