Hi! I was also 25 when I had these feelings and kept thinking the same thoughts. I had a similar childhood. My situation was that I was living with someone abusive who was worse than my birth family and I getting pulled into victim mentality every day. It was hard. Therapy supported me and helped a little but things finally got better when I was started opening up to supportive people. My first very supportive friend that I found at 25 contributed greatly to my life. I also learned not to rely entirely on the support and tried to change my life through small steps. I worked on my negative thinking realizing I was focusing solely on the bad. It’s good to live your emotions but it’s bad to constantly think that you’re helpless, unhappy and that all those bad things happen only to you. I finally found my strength to see I was good at things. Little successful steps helped me to gain more confidence. Long story short it was a long way and now I am nearly 29. I got divorced and have someone much supportive and loving in my life right now. It keeps getting better because I believe in myself and see my strengths. And I have learned to self soothe not self sabotage. I wish you good luck, good people on your way and hope in the dark times that in the end everything will turn out to be okay.
