Personally, I think the first step is to follow the precepts. You can start with the 5 lay precepts, they are fairly easy. Here is my paraphrase, there are many others:
1. Refrain from killing.
2. Refrain from false/harmful speech.
3. Refrain from taking what is not given.
4. Refrain from inappropriate sex.
5. Refrain from intoxication.
This will go a long way to easing the mind. Later, you may wish to cultivate an attitude of kindness.
Second, remember that meditation is not something we just do on the cushion. You should develop attention, presence, and mindfulness in daily life.
Third, learn more about Buddhism and join a sangha (Buddhist group). There are online sanghas as well, and online teachers. This will help develop the "view" that helps understand the process.
Unfortunately, I have found no quick fix. If you want flowers, you need to plant them, tend them, weed them, and let them grow on their own.
