Check with yourself, because sometimes you have been told, that it is impossible so much or many times that you think even the mere act of enquiring; no matter the response is also an impossibility. The fact that you enquired means you asserted yourself and that in itself is a battle won.
Who is surrounding you? What are they saying to you? What are they speaking into your life? Have you ever been told no so many times that you start to doubt if you have any abilities at all. If there is someone making you feel like you are worthless because they constantly speak negatively to you that it leaves you wondering if there is any value in you, that is wrong company. Granted, a few nos or rejections are part of life. But someone can’t constantly and consistently say negative things and call it constructive criticism. No matter how imperfect we can be as people, at least there is one thing or two or more that we do well. You may need to work on becoming better in some areas but it can’t be that everything you do should be criticised; that’s a red flag. Yes, you’ve got to be humble enough to acknowledge and change when you are at fault but be careful with manipulative people.
‘‘Bad company ruins good morals.’’ (1st Corinthians 15:33). You can’t be surrounded by a person or people who suck the very life out of you with their consistently negative comments about you and think you are okay. You have to set boundaries no matter who they are. Boundaries protect us. Even nature itself has boundaries, i.e., water rarely comes to distort the terrestrial land unless its pathway was interfered with. How much more for humans. Protect yourself.
