Cantarella's recommendation is excellent.
The purpose of the Church is the salvation of souls, so it follows that your first and foremost responsibility is the salvation of your own soul, which can only be achieved in a state of grace within the Holy Catholic Church.
You are blessed to have a good conscience and a desire to please God. It sounds like you need a wholesale change in lifestyle, which is quite easy to do when you are motivated by love. You should discuss this with a traditional priest, but if you do not have access, some basics:
You say you are surrounded by sin and temptation, then you must drastically limit your exposure to these people. It's
your responsibility to minimize temptation as much as possible. Here is a sermon on avoiding occasions of sin:

That means you may have to find new friends, and/or limit your visits to family, and/or minimal contact with co-workers.
Severely curtail your participation in the culture (i.e. television, movies, just about every popular music genre) - you are
in the world but not
of the world.
Read more, especially traditional Catholic materials. You have to know the Faith to keep the Faith.
Get out into nature.
Listen to classical music.
Find a healthy hobby, take an interesting course, or volunteer (speak to your priest)
Socialize with those who share your values, not those who are "lying, cheating, stealing, pre-marital sɛҳuąƖ relations, taking the Lord's name in vein at every opportunity, and so forth."
Most importantly, stay in a state of grace. Receive the sacraments as often as possible and stay faithful to your daily prayers.
