I need to stop..

So I need to stop being so jealous and I need to learn to be humble.. I just get so hurt by even vibes I get from other people. I honestly feel like my mother inlaw is starting to like my brother inlaws gf more than me and I know that's an immature thought bc there's no way I could know that without actually asking obviously... It's just hard when this girl comes along literally trying to do everything you do and wanting everything you want and I honestly feel like it's working I feel like she is successfully taking my life away from me. I pray about it and I feel like God is telling me to just humble out. Don't say "Hey stop trying to be me" but to mind my own business and just chill out. Jealousy has always been a huge sin I struggle with and I just want to know if anyone has experienced something similar is all. When I try to tell my husband any of these things that bother me it just turns into an argument.. which is something else I'm always praying about.. Just a little insight from a fellow eve user please. Thank you for reading
