Can I stop trying? I feel fed up.
What are you fed up with?
My life, money, health, and my sex life.
Now and then we reach points in our lives we feel fed up with one aspect or another, but it's important not to dwell on that feeling. If you feel fed up with something, then you need to figure out how you can change it to make it more bearable, otherwise you'll become overwhelmed. If you can't find the solutions on your own, then you should look for a therapist.
I want to cry. I'm now scared that I'm going to live a lonely life.
Things will not always feel like this It is normal to get overwhelmed but you should find resources to get some assistance.
