Should i get drunk tonight?

Don't do it- if you're alone, you could die due to placing yourself in a dangerous situation, trying to commit suicide since your judgment will already be impaired, or passing out and choking on your own vomit unconsciously given you pass out and know one turns you on your side. If you're on your own and you've never done it before, AND you have suicidal thoughts- I strongly recommend that you don't do it. I would seek counseling as well for your depression.
