It's quite hard to give concrete and useful advices over the Internet with vague details. But one technique I see working over and over again across a wide range of disciplines and industries is this: share your feelings with team lead and/or some senior colleagues, preferably in a one-on-one conversation. Many will try to help in some way, some might even become your mentor. Do not be afraid to show your weakness, and your willingness to improve is generally a highly valued attitude. If you get in trouble asking for help, then you are probably surrounded by terrible people and better off with another job anyways.
