As a Catholic, there are generally parishes which are more oriented towards Young Adult ministries, and ones which are more in 'maintenance' mode.
To start, I would obviously say to continue going to Mass, while engaging in spiritual reading which can deepen your understanding and appreciation for the elements of the liturgy which are independent of your particular priest/parish's strengths (like Dom Prosper Gueranger's 'The Liturgical Year,' or David Fagerberg's 'Liturgical Asceticism'). As others have mentioned, the Mass has objective merits which are not dependent on the priest's character, or the community: principally, this is the reception of the Body of Christ in the Eucharist, and the chance to participate in the worship and thanksgiving which God has ordained to be pleasing to Him.
Then, I would start to plan out attending local conferences for Young Adult/Vocational Discernment ministries, attending those, and trying to find out which parishes have very active young adult ministries. Generally, there will be a really popular local Latin Mass group with many young friendly faithful, perhaps run by the Oratorians, or the FSSP, or the ICKSP (depending on your locale). There may also be a very active Byzantine Catholic group, with often attracts young and zealous converts. There will also probably be a few parishes which have an extremely active fellowship program, usually because the priest is hyper-energetic and works tirelessly to cultivate this community. Asking questions at conferences will probably point you in the right direction.
Struggle hard to find the situation that fulfills your needs: "the kingdom of heaven has been subjected to violence, and violent people have been raiding it." The kingdom of heaven is given to those who seek it with violence! Don't be passive.
