I'm tired, so tired.
I feel like I have to work so hard at everything.
I take care of everyone, I put myself last and no one is putting me first.
I don't know how to actually be happy.
I'm great at putting on a smile and acting like life is fine.
Something in me, is always sad and bored and wanting more. More of what? No idea.
I feel like I missed a life lesson and don't know how to live.
Hey Nicole I'm so sorry you are feeling this way
keep reaching out and talking with people who understand without judgement. You deserve to feel happy and content with your life. I hope you find your peace 
I feel the exact same way! Reach out if you’d like a sober friend :). I know I could use one.
Sounds very familiar. I stopped drinking/using for a long time (2 decades), but drank again for these very same feelings. I just go so tired trying to please everyone…and failing. It was never enough and I felt like I wasn’t enough. It got so bad that I needed a “break”. It took a horrific relapse to push me back into a recovery program I had abandoned after the first few years of sobriety. This time around I was broken enough to actually follow the recovery program. I got a sponsor (never had one before), and worked the steps (never got past step 2 before). I found out a lot about myself in the process of working the steps. My DNA will always lead me to being a people pleaser, but today I have boundaries. I’m no longer a prisoner to these destructive feelings. My life is very much the same as it was before. Same wife, kids, family, job, house, bills, responsibilities, etc., but today I’m not overwhelmed by it all. When I start getting squirrelly, I have tools to help me pause the noise in my head. I break that vicious cycle of stinking thinking, and find a path back to living in the solution. I strongly recommend you find a daily recovery program and get to work. I couldn’t think my way out of this. I had to get into action. You can do it too
I know how you feel Nicole,it's just in us to give give give we are a selfless bunch,and I hear you about the insides wanting more....but what of,I don't k own either.
