first of all dont use apps like instagram or tinder to get a relationship because they are doomed to fail. (Only *4.16*% of *Tinder* users are actually looking for a relationship.'')

second you don't need a relationship, you can be happy being single. 

Don't drink alone it is really depressing (done that for a year).

Get some friends and hang out with them, have fun! Just do something with people to take your mind of.
