I have to let this go
Why do you need to let it go?
Because I'm so stressed out about this topic, on the other hand I don't have the energy to continue on with this
If it is stressing you out then let it go, it is okay to let go of something bothering you. Holding onto things of that nature will stress you immensely.
I just don't know how to begin.
I m ight suggest some meditation. Once you feel calm you'll realize it's OK to let the stressful things that are bothering you go.
