Melissa glad you are returning to Psych Central (PC) . Sorry to hear you see yourself with low self esteem.

You wrote: "I just feel comfortable having a low image of myself?" And that is the reason everyone has trouble changing, it is not the easy thing to do. It is outside your comfort zone. It is easier to just diss yourself and think bad thoughts rather than do things that build self esteem.

There are hundred of things you could do to build better self esteem: here are a few. You know the ones that work for you.
clean up my room
eat good food
shower often
dress in clean clothes
do work outside in the yard
help a neighbor
volunteer for a food pantry
go to a religious organization
work at a job
do something you always dreamed of like writing or drawing or music
make a list of the 10 top things you want to do in life.

If you go through this and make your own to do list, already you are closer to higher self esteem. Keep in touch with PC - let us know how you are.
