Need to feel better

Need advice. So I've been having a hell of a time these last 2 years between constant failed relationships to depression struggles etc. And it has had a huge affect on my self worth. I'm started to feel better I even kicked my awful smoking habit which has been a depression crutch for years and it feels good! But I need some advice to feel better and quit this poor me bullshit mindset I've had for the last few years. I'm finally ready to be happy.
