Most of us struggle with how we see ourselves. What we need is to know that God is on our side.
Consider these following points from the Bible:

1. I know God loves me and he has a great plan for my life

2. Yes, I've faults but God is working on me, changing me day by day-
while he does I can still enjoy my life

3.I realise I'll always have issues to deal with, so I wont be
discouraged when God convicts me of areas that still need improvement

4.Everyone has weaknesses, so I'm not a failure because I am not perfect.

5. I want people to like me but my sense of worth is not dependent on
them. No, Jesus has already proven my worth by dying for me.

6. I refuse to be controlled or manipulated by others. Even if they
reject me I'll survice, for Jesus has promised never to leave me or
forsake me.

7.No matter how often I fail I won't give up, because God is with me
to strengthen and sustain me

8.I like myself. I dont like everything I do and I want to change, but
I refuse to reject myself because God loves me and accepts me as I am.

9.In myself I may be nothing but in Christ I'm everything I need to be.
10. I matter to God. My life makes a difference. Regardless of the
challenge,'I can do all things through Christ who strengthens me'
(Phil 4:13)
