Feelings and kamma and sankhara , am I bound for the rest of my life

Are my painful feelings, that I feel now, result of my past kamma (I have for a long period felt extremely painful feelings which I couldn't stop and therefore I am helpless and trapped by them)? Or is it something I am generating by doing something with free will in the present moment, that I am still not aware of that I can stop? Because it seems like I have no way chance against painful feelings and they are controlling me. It seems like it's something there whether I like it or not, it is there autonomous. I am confused, and I am not in control over my feelings, and feeling trapped and helpless to them, because I can't solve them, they feel like a must for me with no way out. Is this kamma what Buddhism talks about, and does this mean I can't solve this? I read that Sankhara are subconscious tendencies. Is that the same as my feelings that keep me trapped? I really want clear understanding what my situation is, and what is my possibility. Will I have to experience this painful feeling the rest of my life? Also is kamma and Sankhara the same thing that keeps me trapped? If not what is the difference? I really need to understand that. Thank you for reading this post.
